Terrapins served with the Royal Engineer assault teams of the 79th Armoured Division and were used to carry infantry units (Canadian and British) over rivers.

[1] A Mark 2 Terrapin with a number of improvements reached the prototype stage, but the war ended before it entered production.

The front and rear wheels provided support and traction on soft surfaces and when climbing slopes, such as riverbanks.

[5] During the operations against Walcheren, Terrapins and Buffalo transports carried the 9th Canadian Infantry Brigade in what was intended to be a diversionary attack across a mile wide inlet on 9 October 1944.

Terrapins were used in Operation Vitality II on 26 October 1944 to carry units from the British 52nd (Lowland) Division across the Scheldt; Amphibious Sherman DD tanks led the attack.
