I've always imagined the usf as the faction that would shine above and beyond with munitions investment vs the usual fuel heavy faction designs. Like, throw up a munitions cache instead of fuel kind of power.
It would create a neat dynamic where usf is trying to deny the enemy fuel and the axis are trying to deny usf ammo.
I'd sooner MORE things follow the design of the AT gun- great unit, fast ROF, amazing vet AND if you invest the MU you have the best pen.
This has the added element of actively engaging the player vs the passive upgrades the game has turned into and allows a good player to make the usf a great faction. Choosing how to make use of your munitions should be a core of the USF imo as their ability to diversely turn a surplus of munitions into a surplus of dead Germans is among the best in the game
That would make for very interesting gameplay, that’s for sure.
You would need to overhaul the faction significantly where:
LVs and tanks are all nerfed in performance, but get significantly beneficial munitions upgrades to bring them to where they are now or more. Their fuel cost would also go down.
Riflemen are slightly nerfed, in exchange for better BARs being available.
Grenades and weapon racks require munitions to unlock
50cal AP rounds become slightly better and more expensive
Vehicle crews could upgrade for munitions to get repair ability.
REs could upgrade to 5men and better rifles for munitions.
LT and Cpt could start as 3man squads and upgrade to 5 for munitions.
In concept this could be interesting, but with how far along we are in the game’s lifespan I don’t think any such overhauls are needed or possible, so usf will remain mostly as is.
