[i play an attacking medic is this game a lot and have quite a few close encounters especially at M-COM stations. The tactic that works well for me is to NOT ADS, but blind fire at almost full auto and use the hit markers to guide your shot. Also a key point is to hold down on the control stick(obviously if PC then the mouse) so it counters the recoil. I have been able to take M-COM stations with 3-4 guys in them camping because the blind fire works quickly and you can swivel your character and dodge much better while not aiming down the sight.
I'm not arguing that works for you, but I would guess I get gunned down 100% of the time when I try this, and when I'm one of the "camping" guys, we win virtually 100% of the time. Blind firing with the LMG
might work against one opponent, particularly with limited visibility, but almost every time I've been involved in a situation like this whether on offense or defense, it ends up being suicide for the attacking player.My usual strategy with M-COMs is to arm it (or let a teammate arm it) and then get a little ways away from it behind some cover. Then I can scope in and pick off people who try to disarm it. I can do that all day by firing the M60 as a semi-auto. Getting in close and relying on full auto to bail me out seldom works. The LMG has too much bullet spread while the SMGs and ARs that storming enemies use tend put me down before I can take out more than one or maybe two guys.
