Mine Clearing System
 
Sherman tanks of the kind equipped with a British mine clearing system, served part of the Israeli armoured forces in the 1950s. The system included heavy chains connected to a drum. As the drum rotated, the chains hit the ground in front of the tank with intense force, therely detonating and blowing up mines, and clearing the axis for the forces advancing at the tank's  heels.
