Oh that's an idea! One of the Officer Squads come with Scoped Rifles and an Assassinate ability. It'll be the Marksmen that USF never had, and historically authentic (around 1/3 of rifle squads had a marksman).
Maybe the other squad could have an M1919, and the ability to become a stationary in one direction, as a makeshift machine gun team. I kinda want this just because M1919's are cool, to be honest.
They are pretty strong and use slots, so they gotta be handled with care, very good vs units out in the open and very bad up close. Unlike most USF weapons.
I like the idea of having the LT be a Grease Gun/Thompson Squad!
They could also use some more interesting skills, if people want to move away from pure damage and numbers, that USF has right now.
