Okay, I know it's not meant for combat and all, but I really think that at the lowest level, these could serve well as the "heavy firepower" for an infantry unit. Say a company of infantry in APCs with a platoon of Krugers to provide some stiffening and longer-range fire. As long as you're facing infantry, some BA, light vehicles, the occasional bug mech, you oughta take no more than acceptable losses.
