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 or "Doodlebug" 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.
Development and use 
In late 1940, after recovering the prototype of a miniature tracked vehicle developed by the French vehicle designer Adolphe Kégresse from the Seine River, the Wehrmacht's ordnance office directed the Carl F.W. Borgward automotive company of Bremen, Germany to develop a similar vehicle for the purpose of carrying a minimum of 50 kg of explosives. The result was the SdKfz. 302 (Sonderkraftfahrzeug, ‘special-purpose vehicle’), called the Leichter Ladungsträger (‘light charge carrier’), or Goliath, which carried 60 kg of explosives. The vehicle was steered remotely via a joystick control box. The control box was attached to the Goliath by a triple-strand cable connected to the rear of the vehicle, for transmitting power to the electric driven version. Two of the strands were used to move and steer the Goliath, the third was used for detonation. The Goliath had 650 m of cable. Each Goliath was disposable, being intended to be blown up with its target. Early model Goliaths used an electric motor but, as these were costly to make (3000 Reichsmarks) and difficult to repair in a combat environment, later models (known as the SdKfz. 303) used a simpler, more reliable gasoline engine.
Goliaths were used on all fronts where the Wehrmacht fought, beginning in spring 1942. They were used principally by specialized Panzer and combat engineer units. Goliaths were used at Anzio in Italy in April 1944. Goliaths were used most notoriously in the Warsaw Uprising of 1944, as Wehrmacht and SS units were deployed to crush fierce Polish resistance by the Polish Home Army (Armia Krajowa). As the Poles had only a small number of antitank weapons, volunteers were often sent to cut off the command cables of the Goliath before it reached its intended target. A few Goliaths were also seen on the beaches of Normandy during D-Day, though most were rendered inoperative due to artillery blasts severing their command cables.
Although a total of 7,564 Goliaths were produced, the single-use weapon was not considered a success due to the high unit cost, low speed (only just above 6 mph, or 9.5 km/h), poor ground clearance (just 11.4 centimeters), vulnerable command cables and thin armour which failed to protect the remote bomb from any form of antitank weapons. However, the Goliath did help lay the foundation for post-World War II advances in remote-controlled vehicle technologies.
