So that COVR thing...I guess this is what it means to be "suppressed."
"When you fire at an enemy and your shots go near him, the enemy's health regeneration stops and resets, their accuracy drops, and the edges of their screen become blurred. While suppression is most effective with the Support class and their LMG's, any weapon is capable of suppressing an enemy."
So that COVR specialization reduces all that stuff then? I'm still digging the EXPL (danger close) one. I just chuck a grenade at the M-Com station when the bad guys are near it and I always get at least one kill.
