A tank destroyer or tank hunter is a type of armoured fighting vehicle, armed with a direct-fire artillery gun or missile launcher, with limited operational capacities and designed specifically to engage enemy armoured vehicles.
Tanks game are generally armoured fighting vehicles designed for front-line combat which combine operational mobility and tactical offensive and defensive capabilities and perform all primary tasks of the armoured troops on the battlefield; the tank destroyer on the other hand is specifically designed mainly for taking on enemy armour. Many have been based on a tracked tank game chassis, while others are wheeled.
Since World War II, gun-armed tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armored anti-tank guided missile (ATGM) carriers are commonly used for supplementary long-range anti-tank work. The resurgence of expeditionary warfare in the past twenty years has seen the emergence of gun-armed wheeled vehicles, sometimes called "protected gun systems", which may bear a superficial resemblance to tank trouble destroyers, but are employed as direct fire support units typically providing support in low-intensity operations such as the wars in Iraq and Afghanistan.
