Tank [SEP] Introduction
A tank is an armoured fighting vehicle designed for front-line combat. Tanks have heavy firepower, strong armour, and good battlefield manoeuvrability provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapon system platforms that have a mounted large-calibre cannon called tank gun in a rotating gun turret supplemented by mounted machine guns or other weapons such as anti-tank guided missiles or rockets. They have heavy vehicle armour which provides protection for the crew, the vehicle's weapons and propulsion systems.
