History
The need for armored support early on during an amphibious invasion was indicated early in the war. It was apparent that there might not be a chance to unload armored vehicles directly on the beaches. This meant that invading armor would need to be unloaded off shore and wade to the beach. In order to do this the tank needed to be waterproofed and a means to supply air to the intakes and to dispel exhaust gases would have to be designed. The answer to this problem was the deep wading kit. These were usually manufactured on site and consisted of a quick release upper stack mounted to a lower stack. The forward stack was for the intake and the rear stack was the exhaust. Once the stacks were in place, the tank was further waterproofed by sealing the transmission, the glacis machine gun, the muzzle of the main gun, the gun shield, hatches, lights and ventilators. Just about anything that could spring a leak was sealed.
