M-32B1 “Earthworm”

In 1943, Gar Wood Industries created an equipment to detonate mines and clear the path to vehicles designated as T1E1 Mine Exploder. The system consisted of three sets of armored rollers of 1.22 meters in diameter mounted in groups of six that were installed on the front of a M-32 or M-32B1 armoured recovery vehicle (ARV) that pushed and controlled the device. The “Earthworm”, as it was nicknamed, weighed 16,560 kg and was very difficult to maneuver. This task was performed with the A-frame crane of the M-32 ARV, which lifted the entire roller system when turning was necessary. The system was practically indestructible and detonated the mines simply by ground pressure. The total production reached 75 units that were sent to Europe in 1944.
