I unlocked the PKM and couldn't be happier with it. My next unlock will be the MP5 replacement. Ironically, I tend to play Medic and Support most often, but I also enjoy the commander role. The SA80 for the medic isn't really an improvement over the M16. The G3 is good, but I don't want to sacrifice the grenade launcher - way too useful. Of course, I have another 6K points before I can unlock another gun anyway.
