I got an idea for the "Western Tribes" (Sioux, Comanche <----(We'll just call it that for now))
Weapon:Shotgun (we'll just have to make due with the grenzers' gun, for now, or try using a rifle/musket because I'm not sure if anybody could "invent" new weapons)
The reloading animation would have to be the Ferguson's rifle animation on horse back.
We'd have to use wayyyy powered-down canister shot for ammo type.
Or give them limited numbers (Both trainable and the actual unit size) and maybe make them crazy expensive.
They'd be able to dismount
Perhaps the eastern tribes (Cherokee and Iroquois), could probalbly have a dismounted version of the unit.
I don't know really, maybe a stupid idea, but nothing funner than having indians murdering white men with shotguns.
