The British did use American weapons as well. I know for a fact that some of the commando and raider forces used Tommyguns (Mark I and II), M1 Garand rifles and M1 Carbines, BARs, Colt 45's, Smith & Wesson revolvers (and probably more I don't know of).

And some American OSS units were in fact issued Stens and Brens. I was kinda hoping to see a Bren in Spearhead (though I doubt it would be any better than the BAR) but ... oh well.

I can't comment on the Russians, though.
