I'd recommend starting as medic. You get alot of points reviving your team and can just sort of sit behind and wait for people to die then run out and revive em and head for cover again and try and keep a medkit out around you always for even more points. Once you get use to using cover you can pop out now and then and lay down some fire. The machine guns have always been pretty strong against infantry because of its uselessness against vehicles or people behind cover ust be sure to fire in burst which really goes for any weapon in BC2 or the accuracy will go to crap (besides the engineers SMGs which have next to no recoil). And with all those points you'll unlock alot of general weapons which recently got beefed up and can now put scopes on em so they're actual viable weapons to use till you unlock some of the higher weapons in the other classes.
