IMO they also need a nondoc infantry squad that can actually be aggressive though. Sections have some of the worst moving acc penalties in the game, are dependent on cover for their RA and DPS bonuses (or rather, un-debuffs), can only be upgraded with LMGs, and are the only nondoc infantry unit in the faction. They need something that can funtion like pgrens.
I think the out of cover penalty shouldn't apply to PIATs tbh. It wouldn't even be a buff so much as making it an actual option; currently the (40% iirc) reload penalty probably makes them one of the worst possible AT infantry units ingame.
I'd go as far as to say that maybe the out of cover penalty should be replaced by an honest to god bonus, but only apply to the enfield rifles.
