An unmanned ground vehicle ( UGV ) is a vehicle that operates while in contact with the ground without an onboard human presence. UGVs can be used for many applications where it is inconvenient, dangerous, expensive, or impossible to use an onboard human operator. Typically, the vehicle has sensors to observe the environment, and autonomously controls its behavior or uses a remote human operator to control the vehicle via teleoperation .

222-673: A German aircraft, carrying a staff officer with the Luftwaffe plans for an offensive through central Belgium to the North Sea, force-landed near Maasmechelen (Mechelen) in Belgium. The documents were captured but Allied intelligence doubted that they were genuine. In the full moon period in April 1940, another Allied alert was called for a possible attack on the Low Countries or Holland, an offensive through
333-612: A German attack in the centre of the French front. After the transfer from the strategic reserve of the Seventh Army to the 1st Army Group, seven divisions remained behind the Second and Ninth armies and more could be moved from behind the Maginot Line. All but one division were either side of the junction of the two armies, GQG being more concerned about a possible German attack past the north end of
444-504: A German force consisting of 43 divisions (32 of them reserves) and no tanks. The French advanced until they met the thin and undermanned Siegfried Line . On 17 September, Gamelin gave the order to withdraw French troops to their starting positions; the last of them left Germany on 17 September, the day of the Soviet invasion of Poland . Following the Saar Offensive, a period of inaction called
555-748: A German invasion of the Netherlands but not Belgium, by changing the deployment area to be reached by the Seventh Army; the Escaut plan would only be followed if the Germans forestalled the French move into Belgium. In the winter of 1939–40, the Belgian consul-general in Cologne had anticipated the angle of advance that Manstein was planning. Through intelligence reports, the Belgians deduced that German forces were concentrating along
666-553: A cable for control, and poor protection against weapons, meant that the Goliath was not considered a success. The first major mobile robot development effort, named "Shakey" , took place during the 1960s as a research study for the U.S. Defense Advanced Research Projects Agency (DARPA). Shakey was a wheeled platform that had a TV camera, sensors, and a computer to help guide its tasks of picking up wooden blocks and placing them in certain areas based on commands. DARPA subsequently developed
777-409: A cannon to carry out reconnaissance and patrol, detect and destroy stationary or moving targets, and provide fire support for security personnel. They are remotely operated.

888-435: A combat zone. The Talon can keep pace with a running soldier. It can operate for 7 days off of one battery charge and is capable of climbing stairs. It was used at Ground Zero during the recovery mission. Talon's durability is attested by one unit that fell off a bridge into a river; the operators turned the control unit back on and drove it out of the river. SWORDS is a Talon robot with an attached weapon system. Shortly after
999-504: A concentration of forces in a position impossible to adequately resupply, along routes that could be cut easily by the French. If the Allies did not react as expected, the German offensive could end in catastrophe. Their objections were ignored and Halder argued that, as Germany's strategic position seemed hopeless anyway, even the slightest chance of decisive victory should be grasped. Shortly before
1110-565: A determined stand on the Somme and Aisne rivers but were defeated by the German combination of air superiority and armoured mobility. Italy entered the war on the German side on 10 June 1940 and began the Italian invasion of France . German armies outflanked the Maginot Line and pushed deep into France, occupying Paris unopposed on 14 June. After the flight of the French government and the collapse of
1221-577: A fall from a helicopter onto concrete. In addition, the SWORDS robot is capable of making its way through difficult terrain, including underwater.

Although the German Army was outnumbered in artillery and tanks, it possessed some advantages over its opponents. The newer German Panzers had a crew of five: commander, gunner, loader, driver, and mechanic. Having
1443-518: A long war in the west. Hitler ordered a conquest of the Low Countries to be executed at the shortest possible notice to forestall the French and prevent Allied air power from threatening the industrial area of the Ruhr . It would also provide the basis for a long-term air and sea campaign against Britain. There was no mention in the directive of a consecutive attack to conquer the whole of France, although
1554-463: A mass firepower effect in attack or defence. The French numerical advantage in heavy weapons and equipment, which was often deployed in "penny-packets" (dispersed as individual support weapons) was offset. Most French tanks also lacked radio and orders between infantry units were typically passed by telephone or verbally. The German communications system permitted a degree of communication between air and ground forces. Attached to Panzer divisions were

An autonomous vehicle must have the ability to: A robot may also be able to learn autonomously. Autonomous learning includes the ability to: Armed autonomous machines must distinguish between combatants and civilians. This is particularly true in conflicts where combatants intentionally disguise themselves as civilians to avoid detection. Even highly accurate but imperfect systems can pose unacceptable civilian losses. The interface between
1776-772: A move towards Breda in the Netherlands; if the Allies prevented a German occupation of Holland, the ten divisions of the Dutch army would join the Allied armies, control of the North Sea would be enhanced and the Germans would be denied bases for attacks on Britain. By May 1940, the 1st Army Group was responsible for the defence of France from the Channel coast south to the Maginot Line. The Seventh Army ( Général d'armée Henri Giraud ), BEF (General Lord Gort ), First Army ( Général d'armée Georges Maurice Jean Blanchard ) and Ninth Army ( Général d'armée André Corap ) were ready to advance to
1887-489: A platoon of Russian UGV's equipped with AGS-17 automatic grenade launchers was deployed for an assault near the town of Berdychi in Ukraine, marking the first ever use of UGV's for direct frontline assaults.

The platform can be a car, truck, all-terrain vehicle , etc., and includes
1998-482: A quick tempo and exploit opportunities faster than the Allies. Panzer divisions could conduct reconnaissance, advance to contact or defend and attack vital positions and weak spots. Captured ground would be occupied by infantry and artillery as pivot points for further attacks. Although many German tanks were outgunned by their opponents, they could lure Allied tanks onto the divisional anti-tank guns. The avoidance of tank-versus-tank engagements conserved German tanks for
2109-564: A radio-based control system he named Telekino . He chose to conduct an initial test in the form of a three-wheeled land vehicle ( tricycle ), which had an effective range of 20 to 30 meters, the first known example of an unmanned ground vehicle.

The ASSCM is a civilian unmanned ground vehicle developed in Yuzuncu Yil University via a grant from TUBITAK (Project code 110M396). The vehicle
2553-417: A trained individual for each task allowed a logical division of labour. French tanks had smaller crews; the commander had to load the main gun, distracting him from observation and tactical deployment. The Germans enjoyed an advantage through the theory of Auftragstaktik (mission command) by which officers, NCOs and men were expected to use their initiative and had control over supporting arms, rather than
2664-463: Is a combination of autonomous and remote operation. A remote-operated UGV is controlled by a human operator. The operator makes decisions based upon either direct visual observation or sensors such as cameras. A basic example of remote operation would be a remote-controlled toy car. Examples: An autonomous UGV (AGV) is an autonomous robot that replaces the human controller with artificial intelligence technologies. The vehicle uses sensors to feed

The car was controlled wirelessly via radio; it was thought the technology could be adapted to tanks. In the 1930s, the USSR developed the Teletank , a small tank, armed with a machine gun. It was remotely controlled by radio from another tank. Teletanks operated in
4107-708: The Albert Canal and increased the readiness of the army; Gamelin and Grand Quartier Général (GQG) began to consider the possibility of advancing further than the Escaut. By November, GQG had decided that a defence along the Dyle Line was feasible, despite the doubts of General Alphonse Georges , commander of the North-Eastern Front, about reaching the Dyle before the Germans. The British had been lukewarm about an advance into Belgium, but Gamelin persuaded them; on 9 November,
4218-749: The Allies failed to fulfil their military obligations to Poland, later called the Western betrayal by the Poles. The possibility of Soviet assistance to Poland had ended with the Munich Agreement of 1938, after which the Soviet Union and Germany eventually negotiated the Molotov–Ribbentrop Pact , which included an agreement to partition Poland. The Allies settled on a long-war strategy in which they would complete

4662-597: The Panzerwaffe should be concentrated at Sedan. This concentration of armour would advance to the west to the English Channel , without waiting for the main body of infantry divisions. This might lead to a strategic collapse of the enemy, avoiding the relatively high number of casualties normally caused by a Kesselschlacht (cauldron battle). Such a risky independent use of armour had been widely discussed in Germany before
4773-727: The Phoney War (the French Drôle de guerre , joke war or the German Sitzkrieg , sitting war) set in between the belligerents. Adolf Hitler had hoped that France and Britain would acquiesce in the conquest of Poland and quickly make peace. On 6 October, in a speech to the Reichstag he made a peace offer to the Western powers. On 9 October 1939, Hitler issued Führer-Directive Number 6 ( Führer-Anweisung N°6 ). Hitler recognised
4884-589: The United Kingdom and France offered military support to Poland in the likely case of a German invasion. At dawn on 1 September 1939, the German invasion of Poland began. France and the United Kingdom declared war on 3 September, after an ultimatum for German forces immediately to withdraw their forces from Poland was not answered. Australia and New Zealand also declared war on 3 September, South Africa on 6 September and Canada on 10 September. While British and French commitments to Poland were met politically,

During World War II, the British developed a radio-controlled version of their Matilda II infantry tank in 1941. Known as "Black Prince", it would have been used for drawing the fire of concealed anti-tank guns, or for demolition missions. Due to the costs of converting
5217-510: The 2011 Fukushima Daiichi Nuclear Power Plant accident, UGVs were used in Japan for mapping and structural assessment in areas with too much radiation to allow a human presence. UGV use by the military has saved many lives. Applications include explosive ordnance disposal (EOD) such as landmines, loading heavy items, and repairing ground conditions under enemy fire. The number of robots used in Iraq increased from 150 in 2004 to 5000 in 2005 where they disarmed over 1000 roadside bombs in Iraq at
5328-413: The 300,000 of the French Army. All of the British Expeditionary Force was motorised. Most of the German logistical transport consisted of horse-drawn vehicles. Only 50 per cent of the German divisions available in 1940 were fit for operations, often being worse equipped than the German army of 1914 or their equivalents in the British and French Armies. In the spring of 1940, the German Army was semi-modern;
5439-400: The Alps took a small amount of ground and after the armistice , Italy occupied a small area in the south-east. The Vichy regime retained the zone libre (free zone) in the south. Following the Allied invasion of French North Africa in November 1942, in Case Anton , the Germans and Italians took control of the zone until France was liberated by the Allies in 1944. During the 1930s,

The German army conducted combined arms operations of mobile offensive formations, with well-trained artillery, infantry, engineer and tank formations, integrated into Panzer divisions. The elements were united by wireless communication, which enabled them to work together at
5661-400: The Army should attack early, ready or not, hoping that Allied unreadiness might bring about an easy victory. Hitler proposed an invasion on 25 October 1939 but accepted that the date was probably unrealistic. On 29 October, Halder presented Aufmarschanweisung N°2, Fall Gelb , with a secondary attack on the Netherlands. On 5 November, Hitler informed Walther von Brauchitsch that he intended

The Seventh Army would take over west of Antwerp, ready to move into Holland and the Belgians were expected to delay a German advance, then retire from the Albert Canal to the Dyle, from Antwerp to Louvain. On the Belgian right, the BEF was to defend about 20 km (12 mi) of the Dyle from Louvain to Wavre with nine divisions and
6216-465: The Dyle plan was adopted. On 17 November, a session of the Supreme War Council deemed it essential to occupy the Dyle Line and Gamelin issued a directive that day detailing a line from Givet to Namur, the Gembloux Gap, Wavre, Louvain and Antwerp. For the next four months, the Dutch and Belgian armies laboured over their defences, the British Expeditionary Force (BEF) expanded and the French army received more equipment and training. Gamelin also considered

On 2 February, Hitler was told of Manstein's plan and on 17 February, Hitler summoned Manstein, General Rudolf Schmundt (Chief of Personnel of the German Army) and General Alfred Jodl , the Chief of Operations of Oberkommando der Wehrmacht (OKW, Supreme Command of the Armed Forces), to a conference. The next day, Hitler ordered Manstein's thinking to be adopted, because it offered
7992-463: The area to be safe from attack, noting it "never favoured large operations". French war games, held in 1938, of a hypothetical German armoured attack through the Ardennes, left the army with the impression that the region was still largely impenetrable and that this, along with the obstacle of the Meuse River , would allow the French time to bring up troops into the area to counter any attack. In 1939,
8103-481: The battle. German tanks had radio receivers that allowed them to be directed by platoon command tanks, which had voice communication with other units. Wireless allowed tactical control and far quicker improvisation than the opponent. Some commanders regarded the ability to communicate to be the primary method of combat and radio drills were considered to be more important than gunnery. Radio allowed German commanders to co-ordinate their formations, bringing them together for
8214-619: The clock, to meet short windows for harvesting. UGVs are used for spraying and thinning. They can be used to monitor crop and livestock health. In the manufacturing environment, UGVs are used for transporting materials. Aerospace companies use these vehicles for precision positioning and transporting heavy, bulky components between manufacturing stations, which is faster than using large cranes and can keep people out of dangerous areas. UGVs can be used to traverse and map mine tunnels. Combining radar, laser, and visual sensors, UGVs are in development to map 3D rock surfaces in open pit mines. In
8325-408: The directive read that as much as possible of the border areas in northern France should be occupied. On 10 October 1939, Britain refused Hitler's offer of peace and on 12 October, France did the same. The pre-war German codename of plans for a campaign in the Low Countries was Aufmarschanweisung N°1, Fall Gelb (Deployment Instruction No. 1, Case Yellow). Colonel-General Franz Halder (Chief of
8436-660: The east (right flank) and attack on the west (left flank) by advancing into Belgium, to fight forward of the French frontier . The extent of the forward move was dependent on events, which were complicated when Belgium ended the Franco-Belgian Accord of 1920 after the German Remilitarisation of the Rhineland on 7 March 1936. The neutrality of the Belgian state was reluctant openly to co-operate with France but information
8547-452: The end of 2005. By 2013, the U.S. Army had purchased 7,000 such machines and 750 had been destroyed. The U.S. military is building UGVs to act as armed robots outfitted with machine guns and grenade launchers that may replace soldiers in combat. Such uses potentially pose ethical concerns by removing humans from the OODA loop . SARGE is a 4-wheel drive all-terrain vehicle that uses the frame of
8658-540: The expense of Army Group B to the north. While Manstein was formulating new plans in Koblenz , Generalleutnant Heinz Guderian , commander of the XIX Army Corps , was lodged in a nearby hotel. Manstein was initially considering a move north from Sedan, directly in the rear of the main Allied mobile forces in Belgium. When Guderian was invited to contribute to the plan during informal discussions, he proposed that most of
8769-480: The field army would have needed more troops than the British Expeditionary Force.) The 88 mm Flak had an elevation of −3° to +85° and could be used as artillery i.e. against panzers. The armies which invaded the west had 85 heavy and 18 light batteries belonging to the Luftwaffe , 48 companies of light Flak integral to divisions of the army and 20 companies of light Flak allocated as army troops,
8880-403: The flanks. Hitler made such a suggestion on 11 November, pressing for an early attack on unprepared targets. Halder's plan satisfied no-one; General Gerd von Rundstedt , the commander of Army Group A ( Heeresgruppe A ) recognised that it did not adhere to the classic principles of Bewegungskrieg ( war of manoeuvre ) that had guided German strategy since the 19th century. A breakthrough
8991-443: The integrity of the national territory and defending without withdrawing the position of resistance organised along the frontier.... giving the 1st Army Group permission to enter Belgium, to deploy along the Escaut according to Plan E. On 24 October, Gamelin directed that an advance beyond the Escaut was only feasible if the French moved fast enough to forestall the Germans. By late 1939, the Belgians had improved their defences along
9102-512: The invasion to begin on 12 November. Brauchitsch replied that the military had yet to recover from the Polish campaign and offered to resign; this was refused but two days later Hitler postponed the attack, giving poor weather as the reason for the delay. More postponements followed, as commanders persuaded Hitler to delay the attack for a few days or weeks, to remedy some defect in the preparations or to wait for better weather. Hitler also tried to alter
9213-525: The invasion, Hitler, who had spoken to forces on the Western Front and who was encouraged by the success in Norway , confidently predicted the campaign would take only six weeks. He was most excited over the planned military glider attack on Fort Eben-Emael . On 3 September 1939, French military strategy had been settled, taking in analyses of geography, resources and manpower. The French Army would defend in
9324-546: The limited Saar Offensive but by mid-October had withdrawn to their start lines. German armies invaded Belgium , Luxembourg , the Netherlands , and France on 10 May 1940. In Fall Gelb ("Case Yellow"), German armoured units made a surprise push through the Ardennes and then along the Somme valley, cutting off and surrounding the Allied units that had advanced into Belgium to meet
9435-676: The locomotive apparatus, sensors, and power source. Tracks, wheels, and legs are common forms of locomotion. The platform may include an articulated body and may join with other units. Power sources can be internal combustion engines, batteries, or hydrogen. Sensors create a model of the environment, showing other vehicles, pedestrians, and obstacles. They also locate the vehicle on the navigation path. Sensors can include compasses, odometers, inclinometers, gyroscopes, cameras, laser and ultrasound rangefinders, GPS radios, and infrared technology. Unmanned ground vehicles are generally considered Remote-Operated or Autonomous, although Supervisory Control
9546-552: The machine and the human operator can include a joystick, autonomous software, or voice commands. Communication between UGV and control station can be done via radio or fiber optics. It may include communication with other machines and robots. The various hardware and software elements must work together to produce desired results. A wide variety of UGVs were in use as of 2024. They typically replace humans in hazardous situations, such as handling explosives and in bomb disabling vehicles , where additional strength or smaller size
9657-473: The main attack against France begin. When Hitler raised objections to the plan and wanted an armoured breakthrough, as had happened in the invasion of Poland, Halder and Brauchitsch attempted to dissuade him, arguing that while the fast-moving mechanised tactics were effective against a "shoddy" Eastern European army, they would not work against a first-rate military like the French. Hitler was disappointed with Halder's plan and initially reacted by deciding that
9768-569: The necessity of military campaigns to defeat the Western European nations, preliminary to the conquest of territory in Eastern Europe, to avoid a two-front war but these intentions were absent from Directive N°6. The plan was based on the seemingly more realistic assumption that German military strength would have to be built up for several years. Only limited objectives could be envisaged and were aimed at improving Germany's ability to survive
9879-503: The next stage of the offensive, units carrying supplies for three to four days' operations. The Panzer divisions were supported by motorised and infantry divisions. German tank battalions ( Panzer-Abteilungen ) were to be equipped with the Panzerkampfwagen III and Panzerkampfwagen IV tanks but shortages led to the use of light Panzerkampfwagen II and even lighter Panzerkampfwagen I instead. The German Army lacked
9990-454: The offensive, including 42 reserve divisions. The German forces in the west in May and June deployed some 2,439 tanks and 7,378 guns. In 1939–40, 45 per cent of the army was at least 40 years old and 50 per cent of all the soldiers had just a few weeks' training. The German Army was far from motorised; ten per cent of their army was motorised in 1940 and could muster only 120,000 vehicles, compared with
10101-456: The plan on 30 January, was only a revision of details. On 24 February, the main German effort was moved south to the Ardennes. Twenty divisions (including seven panzer and three motorised divisions) were transferred from Heeresgruppe B opposite Holland and Belgium to Heeresgruppe A facing the Ardennes. French military intelligence uncovered a transfer of German divisions from the Saar to the north of
10212-432: The plan, which he found unsatisfactory; his weak understanding of how poorly prepared Germany was for war and how it would cope with losses of armoured vehicles were not fully considered. Though Poland had been quickly defeated, many armoured vehicles had been lost and were hard to replace. This led to the German effort becoming dispersed; the main attack would remain in central Belgium, secondary attacks would be undertaken on
10323-612: The possibility of decisive victory. Hitler recognised the breakthrough at Sedan only in tactical terms, whereas Manstein saw it as a means to an end. He envisaged an operation to the English Channel and the encirclement of the Allied armies in Belgium; if the plan succeeded, it could have a strategic effect. Halder then went through an "astonishing change of opinion", accepting that the Schwerpunkt should be at Sedan. He had no intention of allowing an independent strategic penetration by
10434-455: The reaction time for commanders. The Type-X is a 12-tonne tracked and armored robotic combat vehicle designed and produced by Milrem Robotics in Estonia. Measuring 600 cm long, 290 cm wide, and 220 cm tall, this heavy-duty vehicle weighs in at 12,000 kg and can carry a maximum payload of 4,100 kg. It can be fitted with either autocannon turrets up to 50 mm or various other weapons systems, such as ATGMs, SAMs, radars, mortars, etc. The Talon
10545-633: The rearmament plans of the 1930s while fighting a defensive land war against Germany and weakening its war economy with a trade blockade , ready for an eventual invasion of Germany. On 7 September, in accordance with the Franco-Polish alliance , France began the Saar Offensive with an advance from the Maginot Line 5 km (3 mi) into the Saar . France had mobilised 98 divisions (all but 28 of them reserve or fortress formations) and 2,500 tanks against
10656-493: The release of the Warrior, the SWORDS robot was designed and deployed. SWORDS is capable of mounting any weapon system weighing less than 300 pounds. In a matter of seconds, the user can fit weapons such as a grenade launcher, rocket launcher, or 50 caliber machine gun. SWORDS fire with high precision, hitting the bullseye of a target 70/70 times in one test. They are capable of withstanding damage such as multiple 50 caliber rounds, or

10878-518: The seven Panzer divisions of Army Group A. Much to the dismay of Guderian, this element was absent from the new plan, Aufmarschanweisung N°4, Fall Gelb , issued on 24 February. The bulk of the German officer corps was appalled and called Halder the "gravedigger of the Panzer force". Even when adapted to more conventional methods, the new plan provoked a storm of protest from the majority of German generals. They thought it utterly irresponsible to create
10989-466: The slower, top-down methods of the Allies. Army Group B had the support of 1,815 combat aircraft, 487 transport aircraft and 50 gliders; 3,286 combat aircraft supported Army Groups A and C. The Luftwaffe was the most experienced, well-equipped and well-trained air force in the world. The combined Allied total was 2,935 aircraft, about half the size of the Luftwaffe . The Luftwaffe could provide close support with dive-bombers and medium bombers but
11100-575: The transmission system of the tank to Wilson-type gearboxes , an order for 60 tanks was cancelled. From 1942, the German Wehrmacht used the Goliath tracked mine for remote-controlled demolition work. The Goliath was a tracked vehicle carrying 60 kg of explosive charge, directed through a control cable. It modeled a miniature French tracked vehicle found after the German defeat of France in 1940. The combination of cost, low speed, reliance on
11211-692: The war but OKH doubted such an operation could work. Manstein's general operational ideas won immediate support from Guderian, who understood the terrain, having experienced the conditions with the German Army in 1914 and 1918. Manstein wrote his first memorandum outlining the alternative plan on 31 October. In it he avoided mentioning Guderian and played down the strategic part of the armoured units, to avoid unnecessary resistance. Six more memoranda followed between 31 October 1939 and 12 January 1940, each becoming more radical. All were rejected by OKH and nothing of their content reached Hitler. On 10 January 1940,
11322-499: The warehouse management system, UGVs have multiple uses from transferring goods with autonomous forklifts and conveyors to stock scanning and taking inventory. Automated Guided Vehicles are extensively used in warehouses to deal with goods that are dangerous to humans (e.g. corrosive and flammable goods) or need special handling such as passing through freezers. UGVs are used in many emergency situations including urban search and rescue , firefighting, and nuclear response. Following
11433-399: The west of Antwerp and gain the south bank of the Scheldt. The left flank of the 1st Army Group was reinforced by the Seventh Army, containing some of the best and most mobile French divisions, which moved from the general reserve by December. The role of the army was to occupy the south bank of the Scheldt and be ready to move into Holland and protect the estuary by holding the north bank along
11544-508: Was a broadly based force, intended to support national strategy and could carry out operational, tactical and strategic bombing operations. Allied air forces were mainly intended for army co-operation but the Luftwaffe could fly air superiority missions, medium-range interdiction , strategic bombing and close air support operations, depending on circumstances. It was not a Panzer spearhead arm, since in 1939 fewer than 15 per cent of Luftwaffe aircraft were designed for close support as this
11655-413: Was communicated about Belgian defences. By May 1940, there had been an exchange of the general nature of French and Belgian defence plans but little co-ordination against a German offensive to the west, through Luxembourg and eastern Belgium. The French expected Germany to breach Belgian neutrality first, providing a pretext for French intervention or that the Belgians would request support when an invasion
11766-527: Was imminent. Most of the French mobile forces were assembled along the Belgian border, ready to forestall the Germans. An early appeal for help might give the French time to reach the German–Belgian frontier but if not, there were three feasible defensive lines further back. A practicable line existed from Givet to Namur , across the Gembloux Gap ( la trouée de Gembloux ), Wavre , Louvain and along
11877-410: Was needed to encircle and destroy the main body of Allied forces. The most practical place to achieve this would be in the region of Sedan , which lay in the sector of Army Group A. On 21 October, Rundstedt agreed with his chief of staff , Generalleutnant Erich von Manstein , that an alternative operational plan to reflect these principles was needed, by making Army Group A as strong as possible at
11988-428: Was not its main role. The Germans had an advantage in anti-aircraft guns ( Fliegerabwehrkanone [ Flak ]), with 2,600 88 mm (3.46 in) heavy Flak guns and 6,700 37 mm (1.46 in) and 20 mm (0.79 in) . Light Flak refers to the number of guns in the German armed forces, including the anti-aircraft defence of Germany and the equipment of training units. (A 9,300-gun Flak component with

Curiosity landed on Mars in September 2011, and its original two-year mission has since been extended indefinitely. Civilian applications are automating processes in manufacturing environments. They work as autonomous tour guides for the Carnegie Museum of Natural History and the Swiss National Exhibition Expo. UGVs are one type of agricultural robot . Unmanned tractors can operate around
12210-596: Was planned to finish off the French and British after the evacuation at Dunkirk. The Low Countries and France were defeated and occupied by Axis troops down to the Demarcation line , ending land operations on the Western Front until the Normandy landings on 6 June 1944. On 3 September 1939, France and Britain declared war on Germany, over the German invasion of Poland on 1 September. In early September 1939, France began
12321-441: Was to advance through the Low Countries and lure the northern units of the Allied armies into a pocket. It was composed of the 6th and 18th Armies. Army Group C, (General Wilhelm Ritter von Leeb ) comprising 18 divisions of the 1st and 7th Armies, was to prevent a flanking movement from the east and with launching small holding attacks against the Maginot Line and the upper Rhine . Wireless proved essential to German success in
