Churchill Bridge Layer
Bridge Carrying and Pusher Tanks:
Usually tank chassis converted to carry a length of steel bridging to enable armoured formations to cross narrow rivers. Larger rivers required Pontoon bridge sections.
Scissors Bridging Tanks
These converted Tanks carried a hinged double section of steel bridge which was hydraulically pushed into place, folding out as it did so.
Ramp Type Bridging Tanks
These converted tanks were used to drive up to a wall, extend their bridges over their heads and act as a physical ramp for the following armour. These were also known as ARKs.
