That aside, your suggestion is pretty good, but I would say that it has a lot of overlap with Mechanized Company.
Rifle Company should have some sort of buff for Riflemen that is unique to it, but doesn’t fundamentally change the role of Riflemen as a medium range generalist. That’s why I suggested the Veteran Sergeant upgrade with the M1 Carbine. It would make Riflemen better at their intended role of frontline combatant, but not just be some flat DPS boost. Hence the 6th man with a carbine. Thompsons on Riflemen would be too much like Cavalry Riflemen and the Easy Eight is already quite similar to the 76mm Sherman, so it’s best to keep Mechanized Company similarities to a minimum.
In my mind, Rifle Company should offer things to USF that other factions get non-doctrinally, but not gift them with anything too OP. ...
I agree, after thinking about it a bit more, how about this:
Ability 1: Keep Flamethrowers
Ability 2: Riflemen upgrades - Give them a choice of three mutually exclusive upgrades like Tommies get:
a) Thompsons with a 6th man, with the Thompsons taking either one or two slots, plus the OKW infiltration grenades b) an observation package to riflemen which gives them a scoped rifle, better sight, and a sixth man (basically the exact same upgrade as the Fusiliers get) or c) your suggestion of a vet sergeant.
Ability 3: Keep White Phos
Ability 4: Add Time on Target offmap from Infantry company (or better yet the old Mechanized one)
Ability 5: Keep Easy Eight
This would allow a player to adapt Rifles to any situation. One decent offmap, one good offmap, and the Easy Eight would keep the doctrine centered around Rifles with support as needed. I'm always short on munis as USF so the offmaps would have to be used sparingly, which is also okay.
