Anti-tank dog
Anti-tank dogs (Russian: собаки-истребители танков sobaki-istrebiteli tankov or противотанковые собаки protivotankovye sobaki; German: Panzerabwehrhunde or Hundeminen, "dog-mines") were dogs taught to carry explosives to tanks, armored vehicles, and other military targets. They were intensively trained by Soviet military forces between 1930 and 1946, and used from 1941 to 1943 against German tanks in World War II. Initially, dogs were trained to leave a timer-detonated bomb and retreat, but this routine was eventually replaced by an impact-detonation procedure that killed the dog in the process.
