Some difficult stuff I will attempt to add once I'm done with finals

The M249 won't be all that overpowered... it would have the same fire rate as the M16 and the same damage but much worse spread while standing and not being able to run (and not being able to move at all while crouched) will make SAW operators vulnerable to grenades and rpgs and one hit kill weapons like shotguns and sniper rifles (it's hard to dodge a sniper shot when you can barely move). The only advantage is that with the M249 you will have 200 rounds in one belt with the ability to hold an extra 200 round belt.

DeltaStrikeOp, the M249 SAW is not a very good weapon in the hands of the Marines where mobility is number one (Marines usually takes land, the Army usually keeps it). Nobody wants to wait around for guy lugging around light machine guns when quickly taking land is the first priority. However, in the Army, the M249 is still a highly used weapon because suppression is better at defending already taken land and the Army usually uses Humvees to transport their troops around cities rather than lugging around stuff for miles in the wilderness like Marines. It is also why the Marines use the M16 instead of the M4, they usually engage at very long range distances while the Army usually operates in close quarter city environments. So the M249 is not that bad of a weapon, it is just not useful in the eyes of the Marines.
