Another one of "Hobart's Funnies", the Sherman "Crab" Tank.
The "Crab" tank was a modified M4 Sherman tank with a mine flail attached to it. The mine flail was a large drum with chains with weights attached to them The drum would rotate and the chains would pound the ground causing any antipersonnel or antitank mines to detonate. The mine flail would be stored on the back of the tank during transport or when driving to it's destination. When ready for action the mine flail would be raised into the forward position. The tank would clear a path for infantry or other tanks. Countless lives were saved because of these tanks.
