The artist did a really good job here. The submachine-gun on the left was done by @cortz#9 . We never got to naming it, but I always just refer to it as the "Griswold". The rifleman on the right has a "southern cross" badge on his hat, taken from the actual Southern Cross of Honor in OTL. Wanted to give him a bedroll like they had in the Civil War, but this is fine as is I think.
Griswold works. I also imagined the Confederacy having a stamped steel SMG akin to the MP-40, but visually resembling the M3 Grease Gun.
