Sorry Andy, but that's not consistent. There are plenty of units with a rifle in slot 1, and then the same weapon in slot 2, 3, or 4. One of
those guys is brandishing 2 rifles too!

No, it's an additional opportunity to fire in certain instances. This could be, for example, one soldier having more ammunition and directed to fire more often. It could represent the aggregate firepower of a slightly more generous firing policy, or a slightly more elite unit (their fire is more effective). A "third" sniper rifle could be explained in a plethora of ways, just like 3 casualties from 1 sniper firing 1 shot (I've seen it in my China '37 campaign) is explained by a "shot" being a "fire opportunity," not a bullet.
If you have problems with snipers, try Z-fire/area fire. Little to no opfire allowed, and the suppression
seems to be higher... though it could just be the lack of opfire. I never have a problem with a sniper who can't fire.
