Mechanized unit

Armoured warfare, mechanised 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, self-propelled artillery, and other combat vehicles, 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.

Modern armoured warfare began during the First World War 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 usually very slow and caused massive casualties. The development of the tank was motivated by the need to return manoeuvre to warfare, and the only practical way to do so was to provide caterpillar traction to (machine)guns allowing them to overcome trenches while at the same time offering them armour protection against small arms (rifle, machine gun) fire as they were moving.
