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 standardisation 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. The chassis was used for several other combat roles however, such as a flamethrower tank, observation post, and armoured personnel carrier.
The armoured personnel carrier version was known as the Ram Kangaroo.
I remember buying some of Heroics and Ros 1/300th scale Ram Kangaroos back in the 1980s for my Late War British army.
