Which is half the PCs in your party, so I think to the extent we care about realistic weapons, we can ignore heavy machine guns. On the other hand, Ranger HQ might have a few mounted in its guard tower.
In terms of RPG stats for firearms, though, this doesn't exclude weapons like sniper rifles -- they'd weigh a lot, they'd cost a lot, do tremendous single-shot damage, but be slow between shots, to reload (?), and to aim, as well as have the highest penalty (whatever form it might take) to CQB -- and, of course, the longest range and least intrinsic inaccuracy.
For antitank weapons, sticking with the after-the-80's milieu means we can stick with the simpler one-shot weapons of the original game. Maybe "RPGs" (including the LAW and other rockets) would be a better category name, because two-man reusable missile systems like the Javelin, with its 2.5km range and IR seeker, might be a trifle difficult to keep in the same combat model. Heck, at 2.5km, it probably takes more than a single combat round to arrive.
