"Echo 1-4 to 1-6, working on the power systems now," there was blaster fire to be heard over the comm chatter, "encountering plastics in fireteam strength, over." 

"Throw kriffing grenades at them!" Besk hollered over the fight to the troopers. Some might think they'd be overheard, but between the corridors and the shooting and everything else, the sound was drowned out after a certain point. But he'd given them lots of sonic grenades to actually USE the frakking things.

Some of the replacements were so busy just firing hard down the corridors that they forgot the other options they had, but once the shouted order went out, grenades started flying, going off with an incredible racket down the hallways -- the sound of sonic grenades was piercing even outside of the radius, but ringing ears was better than live enemies. He worked his way to the front of the action, near Vannin, and gave a nod, with a grenade already held in one hand opposite the one holding the blaster as the bolts from the Imperials, less than there was fifteen seconds ago, scorched the blast door's frame when the occasional bolt came close, throwing sparks and debris into the air -- that was what blast vests were good for catching...which was also why he went with sonic grenades. They were energy-based and far more likely to be useful against the sort of armor the Imperials wore.
