The M3 GMC saw limited service with other countries as it was not widely supplied through the Lend-Lease program. A small batch of 170 vehicles was supplied to Britain, which used them in their Armoured Car Regiments. They were first used in the Tunisian Campaign with the Royal Dragoons. They were also used in Sicily, Italy, and later in France, but were gradually retired. The Free French Army also used M3s for training before receiving M10 tank destroyers.
