Agreed!
OKW get Panzerfuzies T0, why can't these also be an opening option?!
They probably could be in an doctrine that doesn't have the WC51 in it. Before they get their Thompsons they're about on the level of Assault Engineers.
However, T0 Cav Rifles in a T0 WC-51 would allow USF to drive their opponent off the board in the first couple of minutes. I'd wager that's why Cav Rifles are T1 in the first place.
...and AT satchel should be 30 munitions. It would just be nice to have a starting unit as USF that isn't complete garbage you know.
They do, they're called Riflemen.
