The Hotchkiss 25 mm Anti-Tank Gun came into service with the French Army in 1934. When the British Expeditionary Force went to France in 1939 they had insufficient anti-tank weapons. They were issued with 300 Hotchkiss guns which the all mechanised British Army soon found was not robust enough to be towed behind a vehicle. They had been issued with the horse drawn version of the gun. The gun was used in Portée (carried on the back of a truck) and is believed to be the first gun to be used in that manner.
In British service the gun was known officially as Anti-Tank Gun, 25 mm Hotchkiss, Mark I on 25 mm Carriage, Mark I.
