Yeah, it depends on the writer and the planet those Guards came from. Cadians would probably smoke most unsupported US infantry because of Cadians' brutal training, normal LazGuns, and standard Armor. Basic Bitch Guard Armor can easily stop auto-guns bullets, which are pretty much modern military firearms bullets.

One advantage the Infantrymen would have over the Guards is that the Infantrymen WILL ALWAYS have armor support. Just humvees with 50cals supporting Infantrymen would wreck most Guards that isn't from a Famous Guard world.
