Tank collection at General George Patton military museum American army tanks

A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret.

They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat.

Until the invention of the main battle tank, tanks were typically categorized either by weight class (ultralight, light, medium, heavy or super-heavy tanks) or doctrinal purpose (breakthrough-, cavalry-, infantry-, cruiser-, antinfantry-, antitank-, operational-, qualitative reinforcement-, combined arms-, special operations-, or reconnaissance tanks).
