Anti-tank warfare

Anti-tank warfare arose as a result of the need to develop technology and tactics to destroy tanks during the First World War. Since the first tanks were developed by the allies in 1916 but not principally used till 1917 the first anti-tank weapon was developed by Germany. It was a scaled-up bolt-action rifle designated the Mauser Tank-Gewehr Model 1918 that fired a 13mm cartridge with a solid bullet that could penetrate the thin armor of tanks of the time and destroy the engine or ricochet inside killing occupants. Because tanks represent an enemy's greatest force projection (aside from nuclear artillery and tank vs. tank engagements), anti-tank warfare has been incorporated into the doctrine of nearly every combat service since. The predominant anti-tank weapons at the start of the Second World War were the tank-mounted gun, limbered (towed) anti-tank guns and anti-tank grenades used by the infantry as well as ground-attack aircraft such as the Junkers Ju 87 Stuka.

Anti-tank warfare evolved rapidly, particularly on the Eastern Front, to include new infantry and infantry support weapons such as the bazooka, anti-tank combat engineering, specialized anti-tank aircraft and self-propelled anti-tank guns (tank destroyers). Both the Soviet Red Army and the German Army developed methods of combating tank-led offensives, including deployment of static anti-tank weapons embedded in in-depth defensive positions, protected by anti-tank obstacles and minefields, and supported by mobile anti-tank reserves and ground attack aircraft.

Armoured warfare

Armoured warfare or tank warfare is the use of armoured fighting vehicles in modern warfare. It is a major component of modern methods of war.

The premise of armoured warfare rests on the ability of troops to penetrate conventional defensive lines through use of manoeuvre by armoured units.

Much of the application of armoured warfare depends on the use of tanks and related vehicles used by other supporting arms such as infantry fighting vehicles and self-propelled artillery, as well as mounted combat engineers and other support units. The doctrine of armoured warfare was developed to break the static nature of World War I trench warfare on the Western Front, and return to the 19th century school of thought that advocated manoeuvre and "decisive battle" outcomes in military strategy.

World War I

Modern armoured warfare began with the need to break the tactical, operational and strategic stalemates forced on commanders on the Western Front by the effectiveness of entrenched defensive infantry armed with machine guns—known as trench warfare. Under these conditions, any sort of advance was impossibly slow and occasioned massive casualties. The development of the tank was motivated by the need to return manoeuvre to warfare, and the only way to do so was to protect soldiers from small arms (rifle, machine gun) fire as they were moving.

Tank

A tank is a large, heavily armoured fighting vehicle with tracks and a large tank gun that is designed for front-line combat. Modern tanks are mobile land weapon platforms, mounting a large-calibre cannon in a rotating gun turret. They combine this with heavy vehicle armour which provides protection for the crew, the vehicle's weapons, and its propulsion systems, and operational mobility, due to its use of tracks rather than wheels, which allows the tank to move over rugged terrain and be positioned on the battlefield in advantageous locations. These features enable the tank to perform well in a tactical situation: the combination of powerful weapons fire from their tank gun and their ability to resist enemy fire means the tank can take hold of and control an area and prevent other enemy vehicles from advancing. In both offensive and defensive roles, they are powerful units able to perform key primary tasks required of armoured units on the battlefield. The modern tank was the result of a century of development from the first primitive armoured vehicles, due to improvements in technology such as the internal combustion engine, which allowed the rapid movement of heavy armoured vehicles. As a result of these advances, tanks underwent tremendous shifts in capability during the World Wars of the 20th century.
