I have a USF commander idea.
Commander Name: Please stop spamming vs USF commander
Abilities:
1. Sniper at 0 cps
2. Rear echelons gain access to the same charge paratroopers use at 0 cps.
3. Priests, static arty, or caliopes unlocked after major is researched.
4 Riflemen sandbags and mine
5.(fill with whatever)
I think this will cover most of the holes in the USF faction. Snipers will counter mg and mortar spam on tight maps, rear echelon will have more utility, and USF will have good indirect fire.
