Too Damn Cute IMO 😛
I have the game
You want to use Mosin-Nagant infantry from A&A miniatures for the Red Army - they actually look similar to Civil War-era Reds because the uniform hadn’t changed much in the interim.
Haven’t ordered mine yet. I would suggest the infantry size discrepancy is either an optical illusion or perhaps a subtle attempt by Avalon to aid player’s abiity to distinguish oposing forces on a crowded board.
