Tank is an Armoured Fighting Vehicle designed for Front Line combat, with heavy Firepower, strong armour, and Caterpillar Tracks providing good battlefield manoeuvrability. The first tanks were designed to overcome the deadlock of Trench Warfare now they are a mainstay of modern ground forces and a key part of Combined Arms combat.
Tanks were an important weapons system in World War II. Although Tanks were subject of widespread research in the inter-war years, production was limited to relatively small numbers in a few countries. However, during World War II most armies employed tanks, and production levels reached thousands each month. Tank usage, doctrine and production varied widely among the combatant nations. By war's end, a consensus was emerging regarding tank doctrine and design.
