Seraphim nods satisfactory watching the TESLA's head explode in a splatter in a shower of gore. However I'm going to move to the nearby piece of thick debris from crashed ship to take cover from return fire as I set-up for the next shot. If I can get around to their flank I want to put a bullet from my Gauss rifle into that Heavy's brain pan. I am going to treat this like a sniper would do it. Fire and move position to keep them off their game of wondering who the heck if shooting at them. Give the group inside enough time to catch them in a crossfire with me and them. If I can't get the heavy just yet I'll put down another trooper.
