Conger Mine Clearing Device

This is an experimental Ram tank installed with the Conger Mine clearance device

here is another pic, you can see the conger launch tube and storage for the hose that was then filled with Nitro after it was launched into the minefield

During World War 2 the Sherman Crab was the primary (and most effective) mine clearance vehicle for the 79th Armoured Division, but AVREs carried a range of mine clearance devices to supplement them.

Conger was a similar device, providing a rocket propelled flexible tube that was carried in, and launched from, a converted engineless Universal Carrier towed behind the AVRE. Once in position, the hose was propelled by an attached rocket across the minefield. The tube was pump-filled with a special nitroglycerine based explosive known as 822C. The device was used operationally during the D-Day invasions, but ceased operations after a disaster in the Dutch city of IJzendijke (Explosie bij IJzendijke), in which more than one ton of 822C detonated while being unloaded from two lorries. The explosion caused numerous casualties and destroyed four nearby AVREs, while the lorries "disappeared".
