M1A1 Abrams Tank T-Shirt

The M1 Abrams main battle tank (MBT) became the backbone of the armored forces of the United States military when it was introduced in 1980. Even forty years after it was introduced, the M1 Abrams is considered among the best tanks in the world. 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 good battlefield mobility 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.
