57-554: Military engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications . Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering . In the 20th and 21st centuries, military engineering also includes CBRN defense and other engineering disciplines such as mechanical and electrical engineering techniques. According to NATO , "military engineering

114-521: A better system of training for siege operations was required. On 23 April 1812 an establishment was authorised, by Royal Warrant, to teach "Sapping, Mining, and other Military Fieldworks" to the junior officers of the Corps of Royal Engineers and the Corps of Royal Military Artificers, Sappers and Miners. The first courses at the Royal Engineers Establishment were done on an all ranks basis with

171-476: A dedicated force of military engineering specialists were the Romans, whose army contained a dedicated corps of military engineers known as architecti . This group was pre-eminent among its contemporaries. The scale of certain military engineering feats, such as the construction of a double-wall of fortifications 30 miles (48 km) long, in just 6 weeks to completely encircle the besieged city of Alesia in 52 B.C.E.,

228-477: A given volume in a short duration. Specific military engineering occupations also extend to the field of explosives and demolitions and their usage on the battlefield. Explosive devices have been used on the battlefield for several centuries, in numerous operations from combat to area clearance. Earliest known development of explosives can be traced back to 10th-century China where the Chinese are credited with engineering

285-416: A more acceptable practice. Some examples of these are the ammunition dump and oil depot . Likewise, the military procurement process has much different criteria than the normal business procurement process. Military needs call for reliability of supply during both peace and war, as compared to price and technological factors. Siege of Masada The siege of Masada was one of the final events in

342-501: A number of auxiliary units and Jewish prisoners of war, totaling some 15,000 men and women, of whom an estimated 8,000 to 9,000 were fighting men, to lay siege to the 960 people in Masada. The Roman legion surrounded Masada and built a circumvallation wall, before commencing construction of a siege ramp against the western face of the plateau, moving thousands of tons of stones and beaten earth to do so. Josephus does not record any attempts by

399-539: A popular spectacle for the local people by 1843, when 43,000 came to watch a field day laid on to test a method of assaulting earthworks for a report to the Inspector General of Fortifications. In 1869 the title of the Royal Engineers Establishment was changed to "The School of Military Engineering" (SME) as evidence of its status, not only as the font of engineer doctrine and training for the British Army , but also as

456-400: A technical discipline, the term civil engineering entered the lexicon as a way to distinguish between those specializing in the construction of such non-military projects and those involved in the older discipline. As the prevalence of civil engineering outstripped engineering in a military context and the number of disciplines expanded, the original military meaning of the word "engineering"

513-427: A wall of timber", allowing the Romans to breach the wall of the fortress on April 16, 73 AD. When the Romans entered the fortress, they found it to be "a citadel of death". The Jewish rebels had set all the buildings but the food storerooms ablaze and had killed each other, declaring "a glorious death ... preferable to a life of infamy". According to Josephus, "The Jews hoped that all of their nation beyond

570-498: Is "incomplete and inaccurate" and contradicted by the "skeletons in the cave, and the numerous separate fires". Cohen speculates that "some Jews killed themselves, some fought to the death, and some attempted to hide and escape. The Romans were in no mood to take prisoners and massacred all whom they found." According to Kenneth Atkinson, there is no "archaeological evidence that Masada's defenders committed mass suicide." According to archaeologist Eric H. Cline , Josephus' narrative

627-533: Is a location where supplies, services and materials are located and issued. As a single moving entity, a supply point location is temporary and mobile, normally being occupied for up to 72 hours. Sub-suppliers are those suppliers who provide materials to other suppliers within the supply chain. In other supply chain management contexts they are referred to by tier, second-tier suppliers serving first-tier suppliers, etc. The European Union refers to sub-suppliers in its objective to improve cross-border market access in

684-599: Is an example. Such military engineering feats would have been completely new, and probably bewildering and demoralizing, to the Gallic defenders. Vitruvius is the best known of these Roman army engineers, due to his writings surviving. Examples of battles before the early modern period where military engineers played a decisive role include the Siege of Tyre under Alexander the Great , the Siege of Masada by Lucius Flavius Silva as well as

741-411: Is commonly listed under the role of combat engineers who demolitions expertise also includes mine and IED detection and disposal. For more information, see Bomb disposal . Military engineers are key in all armed forces of the world, and invariably found either closely integrated into the force structure, or even into the combat units of the national troops. Brazilian Army engineers can be part of

798-413: Is impossible because the Romans would have immediately pressed their advantage, leaving no time for Eleazar's speech or the mass suicides. Instead, Cline proposes that the defenders were massacred by Romans. The siege of Masada and the resulting Masada myth is often revered in modern Israel as "a symbol of Jewish heroism". According to Klara Palotai, "Masada became a symbol for a heroic 'last stand' for

855-634: Is now largely obsolete. In its place, the term "military engineering" has come to be used. In ancient times, military engineers were responsible for siege warfare and building field fortifications , temporary camps and roads. The most notable engineers of ancient times were the Romans and Chinese , who constructed huge siege-machines (catapults, battering rams and siege towers ). The Romans were responsible for constructing fortified wooden camps and paved roads for their legions . Many of these Roman roads are still in use today. The first civilization to have

912-435: Is that engineer activity undertaken, regardless of component or service, to shape the physical operating environment. Military engineering incorporates support to maneuver and to the force as a whole, including military engineering functions such as engineer support to force protection, counter-improvised explosive devices, environmental protection, engineer intelligence and military search. Military engineering does not encompass

969-612: The Battle of the Trench under the suggestion of Salman the Persian to dig a trench. For about 600 years after the fall of the Roman empire , the practice of military engineering barely evolved in the west. In fact, much of the classic techniques and practices of Roman military engineering were lost. Through this period, the foot soldier (who was pivotal to much of the Roman military engineering capability)

1026-512: The Brazilian Air Force is occupied by engineers professionalized by Centro de Instrução e Adaptação da Aeronáutica (CIAAR) (Air Force Instruction and Adaptation Center) and trained, or specialized, by Instituto Tecnológico de Aeronáutica (ITA) (Aeronautics Institute of Technology). The Royal School of Military Engineering is the main training establishment for the British Army 's Royal Engineers . The RSME also provides training for

1083-481: The British Army in the conduct of siege operations and bridging. During this war low-ranking Royal Engineers officers carried out large-scale operations. They had under their command working parties of two or three battalions of infantry, two or three thousand men, who knew nothing in the art of siegeworks. Royal Engineers officers had to demonstrate the simplest tasks to the soldiers, often while under enemy fire. Several officers were lost and could not be replaced, and

1140-555: The Churchill AVRE . These and other dedicated assault vehicles were organised into the specialised 79th Armoured Division and deployed during Operation Overlord – 'D-Day'. Other significant military engineering projects of World War II include Mulberry harbour and Operation Pluto . Modern military engineering still retains the Roman role of building field fortifications , road paving and breaching terrain obstacles. A notable military engineering task was, for example, breaching

1197-519: The First Jewish–Roman War and the only person who recorded what happened on Masada. After being captured during the Siege of Yodfat and then freed by Vespasian , Josephus chronicled the Roman campaign. Josephus presumably based his narration on the field commentaries of the Roman commanders. According to Josephus, Masada was first constructed by the Hasmoneans . Between 37 and 31 BC Herod

1254-524: The First Jewish–Roman War , occurring from 72 to 73 CE on and around a hilltop in present-day Israel. The siege is known to history via a single source, Flavius Josephus , a Jewish rebel leader captured by the Romans , in whose service he became a historian. According to Josephus the long siege by the troops of the Roman Empire led to the mass suicide of the Sicarii rebels and resident Jewish families of

1311-451: The Masada fortress. In modern times, the story of the siege was revived as the Masada myth , a selectively constructed narrative based on Josephus's account. The mythical narrative became a national symbol in the early years of Israel 's nationhood. Masada has been described as "a lozenge-shaped table-mountain " that is "lofty, isolated, and to all appearance impregnable". Historically,

These skills provide vital components in the Army's operational capability, and Royal Engineers are currently deployed in Afghanistan , Iraq , Cyprus , Bosnia , Kosovo , Kenya , Brunei , Falklands , Belize , Germany and Northern Ireland . Royal Engineers also take part in exercises in Saudi Arabia , Kuwait , Italy, Egypt , Jordan , Canada, Poland and

1425-508: The Suez Canal during the Yom Kippur War . Military engineers can come from a variety of engineering programs. They may be graduates of mechanical , electrical , civil , or industrial engineering . Modern military engineering can be divided into three main tasks or fields: combat engineering, strategic support, and ancillary support. Combat engineering is associated with engineering on

1482-606: The Zealots and were equally antagonistic to both Romans and other Jewish groups. It was the Zealots, in contrast to the Sicarii, who carried the main burden of the rebellion, which opposed Roman rule of Judea . According to Josephus, on Passover, the Sicarii raided Ein Gedi , a nearby Jewish settlement, and killed 700 of its inhabitants. Archaeology indicates that the Sicarii modified some of

1539-479: The 14th-century development of gunpowder , new siege engines in the form of cannons appeared. Initially military engineers were responsible for maintaining and operating these new weapons just as had been the case with previous siege engines. In England, the challenge of managing the new technology resulted in the creation of the Office of Ordnance around 1370 in order to administer the cannons, armaments and castles of

1596-636: The Euphrates would join together with them to raise an insurrection", but in the end there were only 960 Jewish Zealots who fought the Roman army at Masada. When these Zealots were trapped on top of Masada with nowhere to run, Josephus tells us that the Zealots believed "it [was] by the will of God, and by necessity, that [they] are to die." The Masada site was extensively excavated between 1963 and 1965 by an expedition led by Israeli archaeologist and former military Chief-of-Staff Yigael Yadin . According to Shaye Cohen , archaeology shows that Josephus' account

1653-534: The Great fortified it as a refuge for himself in the event of a revolt. In 66 AD, at the beginning of the First Jewish–Roman War, a group of Jewish extremists called the Sicarii overcame the Roman garrison of Masada and settled there. The Sicarii were commanded by Eleazar ben Ya'ir , and in 70 AD they were joined by additional Sicarii and their families expelled from Jerusalem by the Jewish population with whom

1824-427: The Sicarii to counterattack the besiegers during this process, a significant difference from his accounts of other sieges of the revolt. The ramp was completed in the spring of 73, after probably two to three months of siege. A giant siege tower with a battering ram was constructed and moved laboriously up the completed ramp, while the Romans assaulted the wall, discharging "a volley of blazing torches against ...

1881-543: The Sicarii were in conflict. Shortly thereafter, following the Roman siege of Jerusalem and subsequent destruction of the Second Temple , additional members of the Sicarii and many Jewish families fled Jerusalem and settled on the mountaintop, with the Sicarii using it as a refuge and base for raiding the surrounding countryside. According to modern interpretations of Josephus, the Sicarii were an extremist splinter group of

1938-515: The State of Israel and played a major role for Israel in forging national identity." To Israel, it symbolized the courage of the warriors of Masada, the strength they showed when they were able to keep hold of Masada for almost three years, and their choice of death over slavery in their struggle against an aggressive empire. Masada had become "the performance space of national heritage", the site of military ceremonies. Palotai states how Masada "developed

1995-533: The United States' history of warfare. The Army originally claimed engineers exclusively, but as the U.S. military branches expanded to the sea and sky, the need for military engineering sects in all branches increased. As each branch of the United States military expanded, technology adapted to fit their respective needs. Military transport A supply involves the procurement , distribution , maintenance while in storage , and salvage of supplies, including

2052-646: The United States. The prevalence of military engineering in the United States dates back to the American Revolutionary War when engineers would carry out tasks in the U.S. Army. During the war, they would map terrain to and build fortifications to protect troops from opposing forces. The first military engineering organization in the United States was the Army Corps of Engineers. Engineers were responsible for protecting military troops whether using fortifications or designing new technology and weaponry throughout

2109-501: The ability of defenders to bring fire onto attacking enemies. Fort construction proliferated in 16th-century Europe based on the trace italienne design. By the 18th century, regiments of foot (infantry) in the British, French, Prussian and other armies included pioneer detachments. In peacetime these specialists constituted the regimental tradesmen, constructing and repairing buildings, transport wagons, etc. On active service they moved at

2166-756: The activities undertaken by those 'engineers' who maintain, repair and operate vehicles, vessels, aircraft, weapon systems and equipment." Military engineering is an academic subject taught in military academies or schools of military engineering . The construction and demolition tasks related to military engineering are usually performed by military engineers including soldiers trained as sappers or pioneers . In modern armies, soldiers trained to perform such tasks while well forward in battle and under fire are often called combat engineers . In some countries, military engineers may also perform non-military construction tasks in peacetime such as flood control and river navigation works, but such activities do not fall within

2223-554: The attack on Fort Eben-Emael in Belgium was conducted by Luftwaffe glider -deployed combat engineers. The need to defeat the German defensive positions of the " Atlantic wall " as part of the amphibious landings in Normandy in 1944 led to the development of specialist combat engineer vehicles. These, collectively known as Hobart's Funnies , included a specific vehicle to carry combat engineers,

2280-437: The battlefield. Combat engineers are responsible for increasing mobility on the front lines of war such as digging trenches and building temporary facilities in war zones. Strategic support is associated with providing service in communication zones such as the construction of airfields and the improvement and upgrade of ports, roads and railways communication. Ancillary support includes provision and distribution of maps as well as

2337-441: The concept of logistic management and supply-chain management is the level of information gathered, processes, analysed and used for decision making. An SCM-based organization not only having concerns with its immediate clients but also handles and forecasts the factors affecting directly or indirectly their supplier or suppliers or on their client or clients. If we exclude this information part out of supply chain model then we can see

2394-594: The defence sector. Military logistics is the science of planning and carrying out the movement and maintenance of armed forces . In its most comprehensive sense, those aspects of military operations that deal with: a. design and development , acquisition , storage , movement , distribution , maintenance , evacuation , and disposition of materiel; b. movement, evacuation, and hospitalization of personnel; c. acquisition or construction , maintenance, operation and disposition of facilities; and d. acquisition or furnishing of services. The main difference between

2451-544: The determination of kind and quantity of supplies. United States Department of Defense definitions refer to a "producer phase" and a "consumer phase": A supply chain is a set of linked activities associated with providing material from a raw material stage to an end user as a finished good . Supply control is the process by which an item of supply is controlled within the supply system, including requisitioning, receipt, storage, stock control , shipment , disposition, identification , and accounting . A supply point

2508-525: The director of the Establishment, was keen to confirm his teaching, and regular exercises were held as demonstrations or as experiments to improve the techniques and teaching of the Establishment. From 1833 bridging skills were demonstrated annually by the building of a pontoon bridge across the Medway which was tested by the infantry of the garrison and the cavalry from Maidstone . These demonstrations had become

2565-447: The disposal of unexploded warheads. Military engineers construct bases, airfields, roads, bridges, ports, and hospitals. During peacetime before modern warfare, military engineers took the role of civil engineers by participating in the construction of civil-works projects. Nowadays, military engineers are almost entirely engaged in war logistics and preparedness. Explosives are defined as any system that produces rapidly expanding gases in

2622-796: The end of World War I , the standoff on the Western Front caused the Imperial German Army to gather experienced and particularly skilled soldiers to form "Assault Teams" which would break through the Allied trenches. With enhanced training and special weapons (such as flamethrowers ), these squads achieved some success, but too late to change the outcome of the war. In early WWII, however, the Wehrmacht "Pioniere" battalions proved their efficiency in both attack and defense, somewhat inspiring other armies to develop their own combat engineers battalions. Notably,

2679-502: The fortress could be reached only by a single pathway that was too narrow for men to walk abreast. This pathway was named "the Snake" for the way it twists and zig-zags to the summit. Masada was named as the place where David rested after fleeing from his father-in-law, King Saul . Flavius Josephus , a Jew born and raised in Jerusalem , is the only historian to provide a detailed account of

2736-511: The greatest regard to economy. To reduce staff the NCOs and officers were responsible for instructing and examining the soldiers. If the men could not read or write they were taught to do so, and those who could read and write were taught to draw and interpret simple plans. The Royal Engineers Establishment quickly became the centre of excellence for all fieldworks and bridging. Captain Charles Pasley ,

2793-429: The head of marching columns with axes, shovels, and pickaxes, clearing obstacles or building bridges to enable the main body of the regiment to move through difficult terrain. The modern Royal Welch Fusiliers and French Foreign Legion still maintain pioneer sections who march at the front of ceremonial parades, carrying chromium-plated tools intended for show only. Other historic distinctions include long work aprons and

2850-557: The kingdom. Both military engineers and artillery formed the body of this organization and served together until the office's successor, the Board of Ordnance was disbanded in 1855. In comparison to older weapons, the cannon was significantly more effective against traditional medieval fortifications . Military engineering significantly revised the way fortifications were built in order to be better protected from enemy direct and plunging shot. The new fortifications were also intended to increase

2907-602: The leading scientific military school in Europe. The dawn of the internal combustion engine marked the beginning of a significant change in military engineering. With the arrival of the automobile at the end of the 19th century and heavier than air flight at the start of the 20th century, military engineers assumed a major new role in supporting the movement and deployment of these systems in war. Military engineers gained vast knowledge and experience in explosives . They were tasked with planting bombs, landmines and dynamite . At

2964-401: The logistic management part of the business. Unlike standard supply-chain management practices world-wide, some major concepts are not supported in the military domain. For example, the " just-in-time " (JIT) model emphasizes holding less (or no) inventory, whereas in military supply chains, due to the high costs of a stock-out (potentially placing lives in danger), keeping huge inventory is

3021-499: The right to wear beards. In West Africa , the Ashanti army was accompanied to war by carpenters who were responsible for constructing shelters and blacksmiths who repaired weapons. By the 18th century, sappers were deployed in the Dahomeyan army during assaults against fortifications. The Peninsular War (1808–14) revealed deficiencies in the training and knowledge of officers and men of

3078-441: The scope of military engineering. The word engineer was initially used in the context of warfare, dating back to 1325 when engine’er (literally, one who operates an engine) referred to "a constructor of military engines". In this context, "engine" referred to a military machine, i. e., a mechanical contraption used in war (for example, a catapult ). As the design of civilian structures such as bridges and buildings developed as

3135-448: The structures they found at Masada. These include a building that was modified to function as a synagogue. It may in fact have been a synagogue to begin with, although it did not contain a mikvah or the benches found in other early synagogues. It is one of the oldest synagogues in Israel . In 72 AD, the Roman governor of Judaea, Lucius Flavius Silva , led Roman legion X Fretensis ,

3192-436: The world's first known explosive, black powder . Initially developed for recreational purposes, black powder later was utilized for military application in bombs and projectile propulsion in firearms. Engineers in the military who specialize in this field formulate and design many explosive devices to use in varying operating conditions. Such explosive compounds range from black powder to modern plastic explosives. This particular

3249-657: Was largely replaced by mounted soldiers. It was not until later in the Middle Ages , that military engineering saw a revival focused on siege warfare. Military engineers planned castles and fortresses. When laying siege, they planned and oversaw efforts to penetrate castle defenses. When castles served a military purpose, one of the tasks of the sappers was to weaken the bases of walls to enable them to be breached before means of thwarting these activities were devised. Broadly speaking, sappers were experts at demolishing or otherwise overcoming or bypassing fortification systems. With
