I'd like to see the MG3 from HK. That would be soooo cool. First of all it did acctually exist in 1985, unlike many of the other suggestions. Second it has a higher rof than the PK and M60, and it sounds awesome. FRRRRRRRRR!!!!!!!! It would be fun with a second MG man, to carry ammo, and help setting up. And a gun would be great, especially for the AT soldiers who doesn't normally carry rifles. The HKMP5 could be an alternative, but without the silencer.
