The Katanas are a bit of both, I might add No-Dachis to one of the melee only classes depending on the balance. The modern Imperial troops use the Snider-Enfield rifle (a converted muzzle loaded rifle) which has a bayonet (the same as the other rifles in the mod), however the Japanese troops lack the bayonet as a side arm (which is something all western factions have) but that doesn't really matter. I was thinking of removing the wakisashi from the Imperial Guards and giving them a bayonet side arm instead...
