Thanks!
It was a sort of consolidated decision. Gallians supposed to be an allied faction, so we've decided to use Soviets, because at least they have some big heavy tanks like Is-2 and KV's.
Gallians aren't supposed to be an allied faction but a neutral one. The allied and the axis were fighting south of them. *SPOILER ALERT* But in VC1 The allies tried to kidnap the monarch of Gallia in order to force the Gallians to fight for the allies with the queen as leverage. Gallians are neither allied or axis. The Atlantic Federation are the allied, But the joke is that they never had a appearance in the games with their own uniforms and color schemes as far as I recall. But its suggested in the community that it should be similar to their flag.
ps: Nice skins
