The Trojan Powder Company was an American manufacturer of explosives founded in 1904 that made nitro-starch powder. It had a manufacturing complex in Allentown, Pennsylvania , and another facility at Roberts Landing near San Lorenzo, California .
157-581: The company thrived during World War I (1914–18), continued research and development in the interwar-period, and during World War II operated a large facility in Sandusky, Ohio , under contract to the army. After the war, production scaled back. A facility in Oregon was sold for use by the Trojan Nuclear Power Plant . In 1967, Trojan Powders became a division of Commercial Solvents Corporation (CSC). It
314-511: A Bosnian Serb named Gavrilo Princip assassinated Archduke Franz Ferdinand , heir to the Austro-Hungarian throne. Austria-Hungary held Serbia responsible, and declared war on 28 July. After Russia mobilised in Serbia's defence, Germany declared war on Russia and France , who had an alliance . The United Kingdom entered after Germany invaded Belgium , whose neutrality it guaranteed, and
471-630: A blue-water navy was vital for global power projection; Tirpitz had his books translated into German, while Wilhelm made them required reading for his advisors and senior military personnel. However, it was also an emotional decision, driven by Wilhelm's simultaneous admiration for the Royal Navy and desire to surpass it. Bismarck thought that the British would not interfere in Europe, as long as its maritime supremacy remained secure, but his dismissal in 1890 led to
628-583: A grenade at the Archduke's car and injured two of his aides. The other assassins were also unsuccessful. An hour later, as Ferdinand was returning from visiting the injured officers in hospital, his car took a wrong turn into a street where Gavrilo Princip was standing. He fired two pistol shots, fatally wounding Ferdinand and his wife Sophie . According to historian Zbyněk Zeman , in Vienna "the event almost failed to make any impression whatsoever. On 28 and 29 June,
785-536: A guerrilla warfare campaign and only surrendered two weeks after the armistice took effect in Europe. Before the war, Germany had attempted to use Indian nationalism and pan-Islamism to its advantage, a policy continued post-1914 by instigating uprisings in India , while the Niedermayer–Hentig Expedition urged Afghanistan to join the war on the side of Central Powers. However, contrary to British fears of
942-548: A status quo antebellum. Two weeks after a treaty was signed (but not ratified), Andrew Jackson defeated the British in the Battle of New Orleans and siege of Fort St. Philip with an army dominated by militia and volunteers, and became a national hero. U.S. troops and sailors captured HMS Cyane , Levant and Penguin in the final engagements of the war. Per the treaty, both sides (the United States and Great Britain) returned to
1099-459: A cement manufacturer and one of the organizers of Trojan, used the powder in large quantities. The Panama Canal project used huge quantities of nitrostarch. Walter O. Snelling , who became director of research at Trojan, worked for the U.S. Bureau of Mines on some aspects of the Panama Canal project, and invented a detonator that could be fired underwater. J. B. Bronstein left DuPont and founded
1256-408: A change in policy and an Anglo-German naval arms race began. Despite the vast sums spent by Tirpitz, the launch of HMS Dreadnought in 1906 gave the British a technological advantage. Ultimately, the race diverted huge resources into creating a German navy large enough to antagonise Britain, but not defeat it; in 1911, Chancellor Theobald von Bethmann Hollweg acknowledged defeat, leading to
1413-689: A commercial nitrostarch explosives manufacturing plant in Seiple, Pennsylvania, near Allentown The parent Trojan Safety Powder Company was incorporated in the State of New York in 1906, and became the Trojan Powder Company in 1907. The Pacific High Explosives Company was incorporated in California on 25 April 1906, and built a plant at Roberts Landing in San Leandro, California to manufacture Trojan powder. This
1570-592: A direct threat. The 1908–1909 Bosnian Crisis began when Austria annexed the former Ottoman territory of Bosnia and Herzegovina , which it had occupied since 1878. Timed to coincide with the Bulgarian Declaration of Independence from the Ottoman Empire, this unilateral action was denounced by the European powers, but accepted as there was no consensus on how to resolve the situation. Some historians see this as
1727-634: A few months. The war remains the deadliest conflict in U.S. history, resulting in the deaths of 620,000 men on both sides. Based on 1860 census figures, 8% of all white males aged 13 to 43 died in the war, including 6.4% in the North and 18% in the South . Following the Civil War, the U.S. Army had the mission of containing western tribes of Native Americans on the Indian reservations . They set up many forts, and engaged in

#17329383038761884-530: A functional area. However, officers continue to wear the branch insignia of their former branch in most cases, as functional areas do not generally have discrete insignia. Some branches, such as Special Forces , operate similarly to functional areas in that individuals may not join their ranks until having served in another Army branch. Careers in the Army can extend into cross-functional areas for officers, warrant officers, enlisted, and civilian personnel. Before 1933,
2041-467: A gap between the German armies as they closed on Paris. The French army, reinforced by the British expeditionary corps, seized this opportunity to counter-attack and pushed the German army 40 to 80 km back. Both armies were then so exhausted that no decisive move could be implemented, so they settled in trenches, with the vain hope of breaking through as soon as they could build local superiority. In 1911,

The Army Futures Command (AFC), is a peer of FORSCOM, TRADOC, and AMC, the other ACOMs. AFC's mission is modernization reform: to design hardware, as well as to work within the acquisition process which defines materiel for AMC. TRADOC's mission is to define the architecture and organization of the Army, and to train and supply soldiers to FORSCOM. AFC's cross-functional teams (CFTs) are Futures Command's vehicle for sustainable reform of
2512-540: A possibility. This was accentuated by British and Russian support for France against Germany during the 1911 Agadir Crisis . German economic and industrial strength continued to expand rapidly post-1871. Backed by Wilhelm II, Admiral Alfred von Tirpitz sought to use this growth to build an Imperial German Navy , that could compete with the British Royal Navy . This policy was based on the work of US naval author Alfred Thayer Mahan , who argued that possession of
2669-472: A predominantly combat support role. The army converted to an all-volunteer force with greater emphasis on training to specific performance standards driven by the reforms of General William E. DePuy , the first commander of United States Army Training and Doctrine Command . Following the Camp David Accords that was signed by Egypt, Israel that was brokered by president Jimmy Carter in 1978, as part of
2826-687: A purchase of Trojan Powder, which became a division of CSC. The sale had been agreed in principle on 6 July 1967 by CSC President Robert C. Wheeler and Trojan Powder President Jesse B. Bronstein Jr., who continued as president of the new division. CSC said the Trojan products would be complementary to those of its McWhorter Chemicals division and U. S. Powder Company division. CSC was merged into International Minerals and Chemical Company (IMC) in 1975. The Wolf Lake plant in Union County, Illinois had about 100 employees in
2983-799: A revolt in India, the outbreak of the war saw a reduction in nationalist activity. Leaders from the Indian National Congress and other groups believed support for the British war effort would hasten Indian Home Rule , a promise allegedly made explicit in 1917 by Edwin Montagu , the Secretary of State for India . In 1914, the British Indian Army was larger than the British Army itself, and between 1914 and 1918 an estimated 1.3 million Indian soldiers and labourers served in Europe, Africa, and
3140-613: A role in the invasions of Grenada in 1983 ( Operation Urgent Fury ) and Panama in 1989 ( Operation Just Cause ). By 1989 Germany was nearing reunification and the Cold War was coming to a close. Army leadership reacted by starting to plan for a reduction in strength. By November 1989 Pentagon briefers were laying out plans to reduce army end strength by 23%, from 750,000 to 580,000. A number of incentives such as early retirement were used. In 1990, Iraq invaded its smaller neighbor, Kuwait , and U.S. land forces quickly deployed to assure
3297-579: A satisfactory stable product. A number of permissible nitrostarch-type compounds were approved by the Bureau of Mines. A 1929 letterhead listed offices in Allentown, New York, Chicago, San Francisco and Portland, Oregon. In January 1936, Trojan supplied nitrostarch explosive for test to compare this to TNT for the purpose of demolishing obsolete concrete structures of the Tennessee Valley Authority in

Tensions increased after the 1911–1912 Italo-Turkish War demonstrated Ottoman weakness and led to the formation of the Balkan League , an alliance of Serbia, Bulgaria, Montenegro , and Greece . The League quickly overran most of
3611-705: A strategy of seizing the coastline, blockading the ports, and taking control of the river systems. By 1863, the Confederacy was being strangled. Its eastern armies fought well, but the western armies were defeated one after another until the Union forces captured New Orleans in 1862 along with the Tennessee River. In the Vicksburg Campaign of 1862–1863, General Ulysses Grant seized the Mississippi River and cut off
3768-763: A unified senior living apartment complex. The company experienced a number of explosions, all apparently accidental. World War I World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War , was a global conflict between two coalitions: the Allies (or Entente) and the Central Powers . Fighting took place mainly in Europe and the Middle East , as well as in parts of Africa and
3925-471: A war on two fronts; the Schlieffen Plan envisaged using 80% of the army to defeat France, then switching to Russia. Since this required them to move quickly, mobilization orders were issued that afternoon. Once the German ultimatum to Russia expired on the morning of 1 August, the two countries were at war. At a meeting on 29 July, the British cabinet had narrowly decided its obligations to Belgium under
4082-402: A weak Ottoman government, rather than an ambitious Slav power like Bulgaria . Russia had ambitions in northeastern Anatolia while its clients had overlapping claims in the Balkans. These competing interests divided Russian policy-makers and added to regional instability. Austrian statesmen viewed the Balkans as essential for the continued existence of their Empire and saw Serbian expansion as
4239-451: A whole, the Somme offensive led to an estimated 420,000 British casualties, along with 200,000 French and 500,000 Germans. The diseases that emerged in the trenches were a major killer on both sides. The living conditions led to disease and infection, such as trench foot , lice , typhus , trench fever , and the ' Spanish flu '. At the start of the war, German cruisers were scattered across
4396-729: Is about 4 miles (6.4 km) to the southeast of Springville . Trojan acquired a plant near the entrance to Spanish Fork Canyon, previously owned by Cytec Industries of Delaware and Mallinckdrodt Inc. of New York. Trojan produced nitrostarch there from 1964 to 1976. As of 1967 Trojan had 800 employees. Facilities included plants at Seiple, Pennsylvania, Wolf Lake, Illinois and Springville, Utah . Trojan produced formaldehyde , pentaerythritol , polyols used in alkyd resins, synthetic drying oils, vinyl stabilizers, fire retardant coatings, organic nitrates used in rocket propellants, and inorganic chemicals for various purposes. On September 1, 1967 Commercial Solvents Corporation (CSC) completed

The Army's five core competencies are prompt and sustained land combat, combined arms operations (to include combined arms maneuver and wide–area security, armored and mechanized operations and airborne and air assault operations ), special operations forces , to set and sustain the theater for the joint force, and to integrate national, multinational, and joint power on land. The Continental Army
4867-503: Is known, however, that from 1908 to 1913, military spending by the six major European powers increased by over 50% in real terms. The years before 1914 were marked by a series of crises in the Balkans, as other powers sought to benefit from the Ottoman decline. While Pan-Slavic and Orthodox Russia considered itself the protector of Serbia and other Slav states, they preferred the strategically vital Bosporus straits to be controlled by

As specified before the 2013 end-strength re-definitions, the three major types of brigade combat teams are: In addition, there are combat support and service support modular brigades. Combat support brigades include aviation (CAB) brigades, which will come in heavy and light varieties, fires (artillery) brigades (now transforms to division artillery) and expeditionary military intelligence brigades . Combat service support brigades include sustainment brigades and come in several varieties and serve
5338-558: The Schutzkorps was established, and carried out the persecution of Serbs. The assassination initiated the July Crisis, a month of diplomatic manoeuvring between Austria-Hungary, Germany, Russia, France and Britain. Believing that Serbian intelligence helped organise Franz Ferdinand's murder, Austrian officials wanted to use the opportunity to end their interference in Bosnia and saw war as
5495-626: The World War . In August 1914, the magazine The Independent wrote "This is the Great War. It names itself". In October 1914, the Canadian magazine Maclean's similarly wrote, "Some wars name themselves. This is the Great War." Contemporary Europeans also referred to it as " the war to end war " and it was also described as "the war to end all wars" due to their perception of its unparalleled scale, devastation, and loss of life. The first recorded use of

On 28 October, the German cruiser SMS Emden sank the Russian cruiser Zhemchug in the Battle of Penang . Japan declared war on Germany before seizing territories in the Pacific, which later became the South Seas Mandate , as well as German Treaty ports on
5966-523: The Battle of 73 Easting were tank battles of historical significance. After Operation Desert Storm, the army did not see major combat operations for the remainder of the 1990s but did participate in a number of peacekeeping activities. In 1990 the Department of Defense issued guidance for "rebalancing" after a review of the Total Force Policy, but in 2004, USAF Air War College scholars concluded
6123-857: The Continental Army , which was formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army. The United States Army considers itself a continuation of the Continental Army, and thus considers its institutional inception to be

During the Cold War, U.S. troops and their allies fought communist forces in Korea and Vietnam . The Korean War began in June 1950, when the Soviets walked out of a UN Security Council meeting, removing their possible veto. Under a United Nations umbrella, hundreds of thousands of U.S. troops fought to prevent
6437-570: The Norris Dam area. The conclusion was that nitrostarch had similar performance to TNT at half the price. Although more expensive than dynamite, in some situations it could be a cost-effective alternative. Jesse B. Bronstein Jr., son of the founder, joined Trojan in 1937, and would become its president in 1961. In 1940, the Trojan Powder Company obtained a contract to operate the Plum Brook Ordnance Works in Sandusky, Ohio . Trojan operated

6594-706: The Rüstungswende or 'armaments turning point', when he switched expenditure from the navy to the army. This decision was not driven by a reduction in political tensions but by German concern over Russia's quick recovery from its defeat in the Russo-Japanese War and subsequent 1905 Russian Revolution . Economic reforms led to a significant post-1908 expansion of railways and transportation infrastructure, particularly in its western border regions. Since Germany and Austria-Hungary relied on faster mobilisation to compensate for their numerical inferiority compared to Russia,
6751-622: The San Lorenzo railroad station. The Allentown subsidiary changed its name to the Pennsylvania Trojan Powder Company on 2 October 1909. In 1912, Pacific High Explosives reorganized as California Trojan Powder Company. In 1913 Trojan powder was provided to all primary lookouts in Rogue River National Forest for use in signaling when a fire was seen, assuming the phone lines were out of order. The signalling method
6908-445: The U.S. Army wanted to find an explosive that would be nearly as good as TNT for grenades. Tests summarized in a report of 3 December 1917 showed that the Trojan Explosive was in several ways superior to TNT. Trojan won the contract to make all the powder used in U.S. hand-grenades, and to load the powder into the grenades. The Pennsylvania Trojan Powder Company stepped up expansion of their plants in California and Pennsylvania to create
7065-403: The United States entered the war on the Allied side following Germany's resumption of unrestricted submarine warfare against Atlantic shipping. Later that year, the Bolsheviks seized power in the Russian October Revolution , and Soviet Russia signed an armistice with the Central Powers in December, followed by a separate peace in March 1918. That month, Germany launched an offensive in

During the 1960s, the Department of Defense continued to scrutinize the reserve forces and to question the number of divisions and brigades as well as the redundancy of maintaining two reserve components, the Army National Guard and the Army Reserve . In 1967, Secretary of Defense Robert McNamara decided that 15 combat divisions in
7379-423: The hydrophone and depth charges were introduced, destroyers could potentially successfully attack a submerged submarine. Convoys slowed the flow of supplies since ships had to wait as convoys were assembled; the solution was an extensive program of building new freighters. Troopships were too fast for the submarines and did not travel the North Atlantic in convoys. The U-boats sunk more than 5,000 Allied ships, at
7536-442: The tank . After the First Battle of the Marne in September 1914, Allied and German forces unsuccessfully tried to outflank each other, a series of manoeuvres later known as the " Race to the Sea ". By the end of 1914, the opposing forces confronted each other along an uninterrupted line of entrenched positions from the Channel to the Swiss border. Since the Germans were normally able to choose where to stand, they generally held
7693-588: The 1839 Treaty of London did not require it to oppose a German invasion with military force; however, Prime Minister Asquith and his senior Cabinet ministers were already committed to supporting France, the Royal Navy had been mobilised, and public opinion was strongly in favour of intervention. On 31 July, Britain sent notes to Germany and France, asking them to respect Belgian neutrality; France pledged to do so, but Germany did not reply. Aware of German plans to attack through Belgium, French Commander-in-Chief Joseph Joffre asked his government for permission to cross
7850-431: The 1879 Dual Alliance , which became the Triple Alliance when Italy joined in 1882. For Bismarck, the purpose of these agreements was to isolate France by ensuring the three Empires resolve any disputes between themselves. In 1887, Bismarck set up the Reinsurance Treaty , a secret agreement between Germany and Russia to remain neutral if either were attacked by France or Austria-Hungary. For Bismarck, peace with Russia
8007-441: The 1913 Treaty of London , which had created an independent Albania while enlarging the territories of Bulgaria, Serbia, Montenegro and Greece. However, disputes between the victors sparked the 33-day Second Balkan War , when Bulgaria attacked Serbia and Greece on 16 June 1913; it was defeated, losing most of Macedonia to Serbia and Greece, and Southern Dobruja to Romania. The result was that even countries which benefited from

The U.S. Army is made up of three components: the active component, the Regular Army; and two reserve components, the Army National Guard and the Army Reserve. Both reserve components are primarily composed of part-time soldiers who train once
8321-401: The Army National Guard members were considered state militia until they were mobilized into the U.S. Army, typically at the onset of war. Since the 1933 amendment to the National Defense Act of 1916 , all Army National Guard soldiers have held dual status. They serve as National Guardsmen under the authority of the governor of their state or territory and as reserve members of the U.S. Army under
8478-411: The Army National Guard were unnecessary and cut the number to eight divisions (one mechanized infantry, two armored, and five infantry), but increased the number of brigades from seven to 18 (one airborne, one armored, two mechanized infantry and 14 infantry). The loss of the divisions did not sit well with the states. Their objections included the inadequate maneuver element mix for those that remained and
8635-409: The Austrians and Serbs clashed at the battles of the Cer and Kolubara ; over the next two weeks, Austrian attacks were repulsed with heavy losses. As a result, Austria had to keep sizeable forces on the Serbian front, weakening their efforts against Russia. Serbia's victory against Austria-Hungary in the 1914 invasion has been called one of the major upset victories of the twentieth century. In 1915,
8792-593: The Austrians briefly occupied the Serbian capital, Belgrade . A Serbian counter-attack in the Battle of Kolubara succeeded in driving them from the country by the end of 1914. For the first 10 months of 1915, Austria-Hungary used most of its military reserves to fight Italy. German and Austro-Hungarian diplomats scored a coup by persuading Bulgaria to join the attack on Serbia. The Austro-Hungarian provinces of Slovenia , Croatia and Bosnia provided troops for Austria-Hungary. Montenegro allied itself with Serbia. Bulgaria declared war on Serbia on 14 October 1915 and joined in
8949-493: The Balkan Wars, such as Serbia and Greece, felt cheated of their "rightful gains", while for Austria it demonstrated the apparent indifference with which other powers viewed their concerns, including Germany. This complex mix of resentment, nationalism and insecurity helps explain why the pre-1914 Balkans became known as the " powder keg of Europe ". On 28 June 1914, Archduke Franz Ferdinand of Austria , heir presumptive to Emperor Franz Joseph I of Austria , visited Sarajevo ,

With a decisive victory at Yorktown and the help of the French, the Continental Army prevailed against the British. After the war, the Continental Army was quickly given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became

#17329383038769734-548: The German High Seas Fleet was confined to port. German U-boats attempted to cut the supply lines between North America and Britain. The nature of submarine warfare meant that attacks often came without warning, giving the crews of the merchant ships little hope of survival. The United States launched a protest, and Germany changed its rules of engagement. After the sinking of the passenger ship RMS Lusitania in 1915, Germany promised not to target passenger liners, while Britain armed its merchant ships, placing them beyond

He also considered Dutch neutrality essential for German trade and cancelled the incursion into the Netherlands, which meant any delays in Belgium threatened the viability of the plan. Historian Richard Holmes argues that these changes meant the right wing was not strong enough to achieve decisive success. The initial German advance in
10048-462: The German right wing would sweep through the Netherlands and Belgium , then swing south, encircling Paris and trapping the French army against the Swiss border. The plan's creator, Alfred von Schlieffen , head of the German General Staff from 1891 to 1906, estimated that this would take six weeks, after which the German army would transfer to the East and defeat the Russians. The plan was substantially modified by his successor, Helmuth von Moltke
10205-426: The Germans bled heavily as well, with anywhere from 700,000 to 975,000 casualties between the two combatants. Verdun became a symbol of French determination and self-sacrifice. The Battle of the Somme was an Anglo-French offensive from July to November 1916. The opening day on 1 July 1916 was the bloodiest single day in the history of the British Army , which suffered 57,500 casualties, including 19,200 dead. As

The suffering engendered by the war, as well as the failure of the British government to grant self-government to India afterward, bred disillusionment, resulting in the campaign for full independence led by Mahatma Gandhi . Pre-war military tactics that had emphasised open warfare and individual riflemen proved obsolete when confronted with conditions prevailing in 1914. Technological advances allowed

State militias are both "organized", meaning that they are armed forces usually part of the state defense forces, or "unorganized" simply meaning that all able-bodied males may be eligible to be called into military service. The U.S. Army is also divided into several branches and functional areas . Branches include officers, warrant officers, and enlisted Soldiers while functional areas consist of officers who are reclassified from their former branch into

Currently, the Army is divided into the Regular Army , the Army Reserve, and the Army National Guard . Some states further maintain state defense forces , as a type of reserve to
10990-545: The Ottomans joined the Central Powers in November. Germany's strategy in 1914 was to quickly defeat France, then to transfer its forces to the east, but its advance was halted in September , and by the end of the year the Western Front consisted of a continuous line of trenches stretching from the English Channel to Switzerland. The Eastern Front was more dynamic, but neither side gained a decisive advantage, despite costly offensives. Italy , Bulgaria , Romania , Greece and others joined in from 1915 onward. In April 1917,

The Confederates had the advantage of defending a large territory in an area where disease caused twice as many deaths as combat. The Union pursued
12560-405: The United States Army was maintained as a small peacetime force to man permanent forts and perform other non-wartime duties such as engineering and construction works. During times of war, the U.S. Army was augmented by the much larger United States Volunteers which were raised independently by various state governments. States also maintained full-time militias which could also be called into
12717-678: The West was very successful. By the end of August, the Allied left, which included the British Expeditionary Force (BEF), was in full retreat , and the French offensive in Alsace-Lorraine was a disastrous failure, with casualties exceeding 260,000. German planning provided broad strategic instructions while allowing army commanders considerable freedom in carrying them out at the front, but von Kluck used this freedom to disobey orders, opening
12874-480: The Younger . Under Schlieffen, 85% of German forces in the west were assigned to the right wing, with the remainder holding along the frontier. By keeping his left-wing deliberately weak, he hoped to lure the French into an offensive into the "lost provinces" of Alsace-Lorraine , which was the strategy envisaged by their Plan XVII . However, Moltke grew concerned that the French might push too hard on his left flank and as
13031-423: The acquisition process for the future. In order to support the Army's modernization priorities, its FY2020 budget allocated $ 30 billion for the top six modernization priorities over the next five years.

The Serbian army, fighting on two fronts and facing certain defeat, retreated into northern Albania . The Serbs suffered defeat in the Battle of Kosovo . Montenegro covered
13816-604: The authority of the president, in the Army National Guard of the United States. Since the adoption of the total force policy, in the aftermath of the Vietnam War, reserve component soldiers have taken a more active role in U.S. military operations.

13973-535: The best way of achieving this. However, the Foreign Ministry had no solid proof of Serbian involvement. On 23 July, Austria delivered an ultimatum to Serbia, listing ten demands made intentionally unacceptable to provide an excuse for starting hostilities. Serbia ordered general mobilization on 25 July, but accepted all the terms, except for those empowering Austrian representatives to suppress "subversive elements" inside Serbia, and take part in
14130-483: The border and pre-empt such a move. To avoid violating Belgian neutrality, he was told any advance could come only after a German invasion. Instead, the French cabinet ordered its Army to withdraw 10 km behind the German frontier, to avoid provoking war.

In
14444-583: The campaign saw the first use of anti-aircraft warfare after an Austrian plane was shot down with ground-to-air fire, as well as the first medical evacuation by the Serbian army. Upon mobilisation, in accordance with the Schlieffen Plan , 80% of the German Army was located on the Western Front, with the remainder acting as a screening force in the East. Rather than a direct attack across their shared frontier,

14758-568: The chance of a decisive outcome, while it had failed to achieve the primary objective of avoiding a long, two-front war. As was apparent to several German leaders, this amounted to a strategic defeat; shortly after the First Battle of the Marne , Crown Prince Wilhelm told an American reporter "We have lost the war. It will go on for a long time but lost it is already." On 30 August 1914, New Zealand occupied German Samoa (now Samoa ). On 11 September,

In 1967, Portland General Electric chose the site as the location of the Trojan Nuclear Power Plant . Spanish Fork, Utah
15229-511: The cost of 199 submarines. World War I also saw the first use of aircraft carriers in combat, with HMS Furious launching Sopwith Camels in a successful raid against the Zeppelin hangars at Tondern in July 1918, as well as blimps for antisubmarine patrol. Faced with Russia in the east, Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses,
15386-513: The creation of new independent states, including Poland , Finland , the Baltic states , Czechoslovakia , and Yugoslavia . The League of Nations was established to maintain world peace, but its failure to manage instability during the interwar period contributed to the outbreak of World War II in 1939. Before World War II , the events of 1914–1918 were generally known as the Great War or simply
15543-449: The creation of strong defensive systems largely impervious to massed infantry advances, such as barbed wire , machine guns and above all far more powerful artillery , which dominated the battlefield and made crossing open ground extremely difficult. Both sides struggled to develop tactics for breaching entrenched positions without heavy casualties. In time, technology enabled the production of new offensive weapons, such as gas warfare and
15700-946: The crowds listened to music and drank wine, as if nothing had happened." Nevertheless, the impact of the murder of the heir to the throne was significant, and has been described by historian Christopher Clark as a "9/11 effect, a terrorist event charged with historic meaning, transforming the political chemistry in Vienna". Austro-Hungarian authorities encouraged subsequent anti-Serb riots in Sarajevo . Violent actions against ethnic Serbs were also organised outside Sarajevo, in other cities in Austro-Hungarian-controlled Bosnia and Herzegovina, Croatia and Slovenia. Austro-Hungarian authorities in Bosnia and Herzegovina imprisoned approximately 5,500 prominent Serbs, 700 to 2,200 of whom died in prison. A further 460 Serbs were sentenced to death. A predominantly Bosniak special militia known as

16014-622: The end of FY2017. From 2016 to 2017, the Army retired hundreds of OH-58 Kiowa Warrior observation helicopters, while retaining its Apache gunships. The 2015 expenditure for Army research, development and acquisition changed from $ 32 billion projected in 2012 for FY15 to $ 21 billion for FY15 expected in 2014. By 2017, a task force was formed to address Army modernization, which triggered shifts of units: CCDC , and ARCIC , from within Army Materiel Command (AMC), and Army Training and Doctrine Command (TRADOC), respectively, to
16171-439: The end to the practice of rotating divisional commands among the states that supported them. Under the proposal, the remaining division commanders were to reside in the state of the division base. However, no reduction in total Army National Guard strength was to take place, which convinced the governors to accept the plan. The states reorganized their forces accordingly between 1 December 1967 and 1 May 1968. The Total Force Policy
16328-671: The expansion of the French colonial empire . In 1873, Bismarck negotiated the League of the Three Emperors , which included Austria-Hungary , Russia and Germany.

Germany and Austria-Hungary then formed
16485-400: The first time on the Western Front. Several types of gas soon became widely used by both sides and though it never proved a decisive, battle-winning weapon, it became one of the most feared and best-remembered horrors of the war. In February 1916, the Germans attacked French defensive positions at the Battle of Verdun , lasting until December 1916. Casualties were greater for the French, but
16642-567: The following years, the mission changed from conflict between regular militaries to counterinsurgency , resulting in the deaths of more than 4,000 U.S. service members (as of March 2008) and injuries to thousands more. 23,813 insurgents were killed in Iraq between 2003 and 2011. Until 2009, the army's chief modernization plan, its most ambitious since World War II, was the Future Combat Systems program. In 2009, many systems were canceled, and
16799-569: The forces that landed in French North Africa and took Tunisia and then moved on to Sicily and later fought in Italy . In the June 1944 landings in northern France and in the subsequent liberation of Europe and defeat of Nazi Germany , millions of U.S. Army troops played a central role. In 1947, the number of soldiers in the US Army had decreased from eight million in 1945 to 684,000 soldiers and
16956-638: The front. Serbian and French troops finally made a breakthrough in September 1918 in the Vardar offensive , after most German and Austro-Hungarian troops had been withdrawn. The Bulgarians were defeated at the Battle of Dobro Pole , and by 25 September British and French troops had crossed the border into Bulgaria proper as the Bulgarian army collapsed. Bulgaria capitulated four days later, on 29 September 1918. The German high command responded by despatching troops to hold
17113-661: The geographical status quo. Both navies kept the warships they had seized during the conflict. The army's major campaign against the Indians was fought in Florida against Seminoles . It took long wars (1818–1858) to finally defeat the Seminoles and move them to Oklahoma. The usual strategy in Indian wars was to seize control of the Indians' winter food supply, but that was no use in Florida where there
17270-526: The globe, some of which were subsequently used to attack Allied merchant shipping . These were systematically hunted down by the Royal Navy, though not before causing considerable damage.

17741-534: The high ground, while their trenches tended to be better built; those constructed by the French and English were initially considered "temporary", only needed until an offensive would destroy the German defences. Both sides tried to break the stalemate using scientific and technological advances. On 22 April 1915, at the Second Battle of Ypres , the Germans (violating the Hague Convention ) used chlorine gas for
17898-467: The investigation and trial of Serbians linked to the assassination. Claiming this amounted to rejection, Austria broke off diplomatic relations and ordered partial mobilisation the next day; on 28 July, they declared war on Serbia and began shelling Belgrade .

18369-569: The line, but these forces were too weak to re-establish a front. United States Army The United States Army ( USA ) is the land service branch of the United States Armed Forces . It is one of the eight U.S. uniformed services , and is designated as the Army of the United States in the U.S. Constitution . The Army is the oldest branch of the U.S. military and the most senior in order of precedence. It has its roots in
18526-406: The mission of the U.S. Army is "to fight and win our Nation's wars, by providing prompt, sustained land dominance, across the full range of military operations and the spectrum of conflict, in support of combatant commanders ". The branch participates in conflicts worldwide and is the major ground-based offensive and defensive force of the United States of America. The United States Army serves as
18683-449: The new army. A number of European soldiers came on their own to help, such as Friedrich Wilhelm von Steuben , who taught Prussian Army tactics and organizational skills. The Army fought numerous pitched battles, and sometimes used Fabian strategy and hit-and-run tactics in the South in 1780 and 1781; under Major General Nathanael Greene , it hit where the British were weakest to wear down their forces. Washington led victories against
18840-592: The new nation's sole ground army, except a regiment to guard the Western Frontier and one battery of artillery guarding West Point 's arsenal. However, because of continuing conflict with Native Americans , it was soon considered necessary to field a trained standing army. The Regular Army was at first very small and after General St. Clair's defeat at the Battle of the Wabash, where more than 800 soldiers were killed,
18997-460: The ocean, even to neutral ships. Since there was limited response to this tactic, Germany expected a similar response to its unrestricted submarine warfare. The Battle of Jutland in May/June 1916 was the only full-scale clash of battleships during the war, and one of the largest in history. The clash was indecisive, though the Germans inflicted more damage than they received; thereafter the bulk of
19154-465: The origin of that armed force in 1775. The U.S. Army is a uniformed service of the United States and is part of the Department of the Army , which is one of the three military departments of the Department of Defense .

19311-436: The protection of Saudi Arabia . In January 1991 Operation Desert Storm commenced, a U.S.-led coalition which deployed over 500,000 troops, the bulk of them from U.S. Army formations, to drive out Iraqi forces . The campaign ended in total victory, as Western coalition forces routed the Iraqi Army . Some of the largest tank battles in history were fought during the Gulf war. The Battle of Medina Ridge , Battle of Norfolk and
19468-681: The protection of the " cruiser rules ", which demanded warning and movement of crews to "a place of safety" (a standard that lifeboats did not meet). Finally, in early 1917, Germany adopted a policy of unrestricted submarine warfare , realising the Americans would eventually enter the war. Germany sought to strangle Allied sea lanes before the United States could transport a large army overseas, but, after initial successes, eventually failed to do so. The U-boat threat lessened in 1917, when merchant ships began travelling in convoys , escorted by destroyers . This tactic made it difficult for U-boats to find targets, which significantly lessened losses; after
19625-412: The remaining were swept into the BCT modernization program . By 2017, the Brigade Modernization project was completed and its headquarters, the Brigade Modernization Command, was renamed the Joint Modernization Command, or JMC.

20096-413: The service of the army. By the twentieth century, the U.S. Army had mobilized the U.S. Volunteers on four occasions during each of the major wars of the nineteenth century. During World War I, the " National Army " was organized to fight the conflict, replacing the concept of U.S. Volunteers. It was demobilized at the end of World War I and was replaced by the Regular Army, the Organized Reserve Corps, and
20253-456: The services follows a chain of command from the president to the secretary of defense directly to the unified combatant commanders , who have control of all armed forces units in their geographic or function area of responsibility, thus the secretaries of the military departments (and their respective service chiefs underneath them) only have the responsibility to organize, train and equip their service components. The army provides trained forces to
20410-415: The side of Britain , France , Russia , Italy and the other Allies . U.S. troops were sent to the Western Front and were involved in the last offensives that ended the war.

The Regular Army, Army of the United States, the National Guard, and Officer/Enlisted Reserve Corps (ORC and ERC) existed simultaneously. After World War II,
20724-402: The states of California , Nevada , Utah , Colorado , Arizona , Wyoming and New Mexico . The American Civil War was the costliest war for the U.S. in terms of casualties.

After repeated advances and retreats by both sides and the Chinese People's Volunteer Army 's entry into the war, the Korean Armistice Agreement returned the peninsula to the status quo in July 1953. The Vietnam War is often regarded as a low point for the U.S. Army due to the use of drafted personnel ,
21195-415: The term First World War was in September 1914 by German biologist and philosopher Ernst Haeckel who stated, "There is no doubt that the course and character of the feared 'European War' ... will become the first world war in the full sense of the word." For much of the 19th century, the major European powers maintained a tenuous balance of power , known as the Concert of Europe . After 1848, this
21352-584: The threat posed by the closing of this gap was more important than competing with the Royal Navy. After Germany expanded its standing army by 170,000 troops in 1913, France extended compulsory military service from two to three years; similar measures were taken by the Balkan powers and Italy, which led to increased expenditure by the Ottomans and Austria-Hungary. Absolute figures are difficult to calculate due to differences in categorising expenditure since they often omit civilian infrastructure projects like railways which had logistical importance and military use. It
21509-417: The total number of active divisions had dropped from 89 to 12. The leaders of the Army saw this demobilization as a success. In the Pacific War , U.S. Army soldiers participated alongside the United States Marine Corps in capturing the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, army troops were deployed to Japan and Germany to occupy
21666-676: The two defeated nations. Two years after World War II, the Army Air Forces separated from the army to become the United States Air Force in September 1947. In 1948, the army was desegregated by order 9981 of President Harry S. Truman . The end of World War II set the stage for the East–West confrontation known as the Cold War . With the outbreak of the Korean War , concerns over the defense of Western Europe rose. Two corps, V and VII , were reactivated under Seventh United States Army in 1950 and U.S. strength in Europe rose from one division to four. Hundreds of thousands of U.S. troops remained stationed in West Germany, with others in Belgium ,
21823-452: The unpopularity of the war with the U.S. public and frustrating restrictions placed on the military by U.S. political leaders.

U.S. forces effectively established and maintained control of the "traditional" battlefield, but they struggled to counter
21980-429: The war ended with the Armistice of 11 November 1918 . The Paris Peace Conference of 1919–1920 imposed settlements on the defeated powers, most notably the Treaty of Versailles , by which Germany lost significant territories, was disarmed, and was required to pay large war reparations to the Allies. The dissolution of the Russian, German, Austro-Hungarian, and Ottoman Empires redrew national boundaries and resulted in
22137-413: The war involved British, French, and German colonial forces in Africa. On 6–7 August, French and British troops invaded the German protectorates of Togoland and Kamerun . On 10 August, German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the rest of the war. The German colonial forces in German East Africa , led by Colonel Paul von Lettow-Vorbeck , fought
22294-418: The west , which despite initial successes left the German Army exhausted and demoralised. A successful Allied counter-offensive from August 1918 caused a collapse of the German front line.

These included trinitrotoluene (TNT), dinitrotoluene (DNT), and pentolite . The factory operated around the clock, seven days a week throughout the remainder of the war. The United States Army Ordnance Department took back control of the site in December 1945 and started decontamination. Snelling represented Trojan at Plum Brook. In 1942, he discovered
22608-417: The world in size. General George C. Marshall became Army chief of staff in September 1939 and set about expanding and modernizing the Army in preparation for war. The United States joined World War II in December 1941 after the Japanese attack on Pearl Harbor . Some 11 million Americans were to serve in various Army operations. On the European front , U.S. Army troops formed a significant portion of
22765-432: Was a major factor in the deadly Spanish flu pandemic. The causes of World War I included the rise of Germany and decline of the Ottoman Empire , which disturbed the long-standing balance of power in Europe, as well as economic competition between nations triggered by industrialisation and imperialism . Growing tensions between the great powers and in the Balkans reached a breaking point on 28 June 1914, when
22922-421: Was a member of the board of Pennsylvania Trojan Powder Company. In 1917 William E. Hall was president of the Trojan Powder Company, the Trojan Chemical Company and the Stackpole Carbon Company. Walter O. Snelling (1880–1965), a scientist with the U.S. Geological Survey (1907–10) and the Bureau of Mines (1910–12) joined the Trojan Powder Company in 1917 after a period of self-employment. The Ordnance Department of
23079-439: Was adopted by Chief of Staff of the Army General Creighton Abrams in the aftermath of the Vietnam War and involved treating the three components of the army – the Regular Army , the Army National Guard and the Army Reserve as a single force. General Abrams' intertwining of the three components of the army effectively made extended operations impossible without the involvement of both the Army National Guard and Army Reserve in
23236-403: Was challenged by Britain's withdrawal into so-called splendid isolation , the decline of the Ottoman Empire , New Imperialism , and the rise of Prussia under Otto von Bismarck . Victory in the 1870–1871 Franco-Prussian War allowed Bismarck to consolidate a German Empire .

23393-433: Was created on 14 June 1775 by the Second Continental Congress as a unified army for the colonies to fight Great Britain , with George Washington appointed as its commander. The army was initially led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them. As the Revolutionary War progressed, French aid, resources, and military thinking helped shape
23550-488: Was later acquired by the Ensign-Bickford Company. Chemists F.B. Holmes and Jesse B. Bronstein discovered how to produce a stable nitrostarch while working at DuPont 's Eastern Laboratories. Between 1905 and 1908, Holmes obtained various patents related to stabilization of nitrostarch powders. Because the powder did not contain glycerol , it would not freeze and was non-toxic. The powder quickly became widely used for mining, tunneling and quarrying. General Harry C. Texler,
23707-411: Was never put to the test, and a report on the experiment was highly skeptical about whether it would have worked. An advertisement on 17 May 1913 for the Trojan Powder Company of Allentown, PA. listed the principal sales offices as New York City, San Francisco, Salt Lake City, Denver and Portland, Oregon . The company had powder mills in Allentown, California. and Colorado. During World War I (1914–18)
23864-436: Was no winter. The second strategy was to form alliances with other Indian tribes, but that too was useless because the Seminoles had destroyed all the other Indians when they entered Florida in the late eighteenth century.

The U.S. victory resulted in acquisition of territory that eventually became all or parts of
24021-528: Was procured and stored. The War of 1812 , the second and last war between the United States and Great Britain, had mixed results. The U.S. Army did not conquer Canada but it did destroy Native American resistance to expansion in the Old Northwest and stopped two major British invasions in 1814 and 1815. After taking control of Lake Erie in 1813, the U.S. Army seized parts of western Upper Canada, burned York and defeated Tecumseh , which caused his Western Confederacy to collapse. Following U.S. victories in
24178-654: Was refused. Early on the morning of 4 August, the Germans invaded, and Albert I of Belgium called for assistance under the Treaty of London . Britain sent Germany an ultimatum demanding they withdraw from Belgium; when this expired at midnight, without a response, the two empires were at war. Germany promised to support Austria-Hungary's invasion of Serbia, but interpretations of what this meant differed. Previously tested deployment plans had been replaced early in 1914, but those had never been tested in exercises. Austro-Hungarian leaders believed Germany would cover its northern flank against Russia. Beginning on 12 August,
24335-600: Was returning to Germany when it sank two British armoured cruisers at the Battle of Coronel in November 1914, before being virtually destroyed at the Battle of the Falkland Islands in December. The SMS Dresden escaped with a few auxiliaries, but after the Battle of Más a Tierra , these too were either destroyed or interned. Soon after the outbreak of hostilities, Britain began a naval blockade of Germany . This proved effective in cutting off vital supplies, though it violated accepted international law. Britain also mined international waters which closed off entire sections of
24492-586: Was the foundation of German foreign policy but in 1890, he was forced to retire by Wilhelm II . The latter was persuaded not to renew the Reinsurance Treaty by his new Chancellor , Leo von Caprivi . This gave France an opening to agree the Franco-Russian Alliance in 1894, which was then followed by the 1904 Entente Cordiale with Britain. The Triple Entente was completed by the 1907 Anglo-Russian Convention . While not formal alliances, by settling long-standing colonial disputes in Asia and Africa, British support for France or Russia in any future conflict became
24649-429: Was the only western plant of the New York-based Trojan Powder Company. On November 23, 1906, most of the apparatus for the new Trojan powder works at Overton, eight miles north of Pueblo, Colorado had arrived. The buildings were almost completed and it was thought that the manufacture of powder would be started before 1 December. The products of the Trojan Powder Factory were shipped on the Southern Pacific railway from
