G'Day (Sentinel)

The Cruiser Sentinel Mark I was Australia's first tank. It was designed so that in the event Australia was cutoff from her allies, she could still produce armor. Based on the U.S. M3 chassis, it's a blend of American tracks & 3 Cadillac engines, British weapons and a French suspension. Though it never saw combat, the Sentinel was used in training until 1956. It is unconfirmed if it was powered by Vegemite.
