candian tanks

A Kangaroo was a Second World War Commonwealth or British armoured personnel carrier (APC), created by converting a tank chassis. Created as an expedient measure by the Canadian Army, Kangaroos were so successful that they were soon being used by British forces.

Their ability to manoeuvre in the field with the tanks was a major advantage over earlier designs, and led to the dedicated APC designs that were introduced by almost all armies immediately after the war.
