The Tank, Cruiser, Ram was a cruiser tank designed and built by Canada in the Second World War, based on the U.S. M3 Medium tank chassis. Due to standardization on the American Sherman tank for frontline units, it was used exclusively for training purposes and was never used in combat as a gun tank.
This Ram tank was at Bovington.
The chassis was used for several other combat roles however, such as a flamethrower tank, observation post, and armoured personnel carrier. There was a Ram Kangaroo at the museum as well.
I remember buying some of Heroics and Ros 1/300th scale Ram Kangaroos back in the 1980s for my Late War British army.
