At the beginning of World War II the British Armed Forces took delivery of 330 militarised Leyland Hippos with an open military cabs and bodies, known in service as the Hippo Mk I or the WSW17. In 1943, as a result of D-Day preparations, Leyland commenced designing an updated version, the Hippo Mk II. Production commenced in 1944 and roughly 1,000 were in service by VE Day. They remained in British service into the 1970s.[3][4]
