well, then let's make it a little unique:
I proposed just giving them the pak40 years ago. I got shouted down for wanting the game to be age of empires
clone the usf at gun
make it come after first truck call in
remove the pen round ability
add current preview cloack and first strike bonus to give it 50% more accuracy and pen for the first shoot
tada it's unique now and perfect counter to early LV and LT thanks to bonus accuracy for the first shoot
adjust the vet now with some pen buff here and there
