The Goliath tracked mine - complete German name: Leichter Ladungsträger Goliath (Sd.Kfz. 302/303a/303b) - was a remote controlled German-engineered demolition vehicle, also known as the beetle tank to the Allies.
Employed by the Wehrmacht during World War II, this caterpillar-tracked vehicle was approximately 4 feet (1.2 m) long, 2 feet (0.61 m) wide, and 1 foot (0.30 m) tall. It carried 75–100 kilograms (170–220 lb) of high explosives and was intended to be used for multiple purposes, such as destroying tanks, disrupting dense infantry formations, and demolition of buildings and bridges.
