Bison Concrete Armoured Lorry - Need

Need

With the Fall of France in July 1940, the British Government made efforts to prepare for the threatened invasion. One problem was the defence of airfields against airborne troops.

An ideal solution for protecting the open space of an airfield was by tanks and armoured cars. However, the British Army lacked heavy equipment, having abandoned much of it during the evacuation of Dunkirk. An alternative was needed which would not compete for resources with conventional armaments.

The Bison was effectively a mobile pillbox that could be driven to defensive positions when needed, or even used to block runways against landings.
