the japanese weapons all begin with 'type' something, and you are right, there are no japanese in breakthrough, so that leaves the bren gun. it looks like it says vickers on it, but the vickers was a world war 1 mg. i think this one is a lighter version of it, but it was common to have ww1 era weapons used in ww2 cause they didnt develope many new weapons until the war started.
