i just logged into that Battlelog thing where it shows you your stats/next unlocks etc.
Good lord.... my stats are brutal.
I'm only at a level 19; and need some more unlocks with my support weapons.
Apparently I'm close to a foregrip on my M60, so I think I'm going to try to knock that out and see if that helps. Got some upcoming goodies on the M240. I've notice that I use that PKP ALOT. I need to play around with the others more.
