tank destroyer; self-propelled anti-tank gun
Military vehicle designed specifically to engage and destroy enemy tanks, typically with a powerful gun mounted on a tracked chassis.
During World War II, the German military deployed many tank destroyers.
Tank destroyers often have thinner armor than tanks.
戦車 is a general-purpose tank, while 駆逐戦車 is a specialized vehicle designed primarily to destroy tanks.
対戦車自走砲 is a more technical term for self-propelled anti-tank gun, essentially synonymous with 駆逐戦車.
Compound of 駆逐 (kuchiku, 'expulsion, driving out') and 戦車 (sensha, 'tank'), literally 'expulsion tank'. The term is a calque from English 'tank destroyer' or German 'Jagdpanzer'.
