rifleman only has 1 good class skill and that's dig in, rifle damage and tank damage aren't so great, I'd rather take more ammo and melee/health.
Yeah they got shitty skills, should be meshed with the scouts. But rifles completely mow down infantry. Easily, grens actually need the resists to be able to be effective. If they had less range and dps on those rifles then I would be all for raising the resists.
