Ga'duk was not scared of the raging conflict, persay, it was chaotic and confusing and he was starting to have a very difficult time figuring friend from foe. Nobody was wearing an imperial guard uniform or any kind of standardized equipment, it was very difficult. Thorn came to his rescue giving him a direction and orders. Simple orders he could follow. However it meant wading through the bloodiest portion of the battle. The sisters were wavering under the combined assault from the genestealers and the new Chaos marines, but they hadnt broken. Ga'duk nodded at Thorn, "OK BOSS" he shouted over the cacophony of bolters and chain swords. He peeked around the corner for a moment and rolled his shoulders adjusting the comfort of his armor preparing for a very exciting next few moments. 

He took a step forward to charge head long into the fray, and paused to bellow a barbaric warcry that ecoed through the halls over even the bolter fire. Several battle sisters jerked towards him training their bolters on him as he charged. Most of the shells detonated on the walls behind him with only a few finding their mark, the sisters exhaustion and surprise making their aim waiver. The few shells that did hit their mark shrugged off his armor saving his life. When Ga'duk reached the sisters he hit them like a Squiggoth, shoving them aside making a hole for himself and the others. He did not slow and kept pushing forward, using his weight and strength to toss any assailant away or simply bowl them down. His momentum stopped suddenly in the midst of the fray when he suddenly found a Chaos Marine in his path with a whirring chain sword carving though his armor and biting flesh. Ga'duk howled in suprise and pain reaching out and grabbing the marine by the breast plate with one hand and the marine's sword arm with the other, dropping both his axe and grenade gauntlet. Without thinking he began pulling the two apart with all his strength, not noticing the several bolter shells detonating against his armor rendering it nearly destroyed. With a sickening crack of breaking bone and ceramite the Marine's arm came free.

Ga'duk dropped the arm and hurled the wounded marine with all his strength in the direction of the other fleeing party, using the broken soldier as a wrecking ball creating a path through the rest of the battle. Before taking advantage of the newly created hole he reached down and picked up his axe. He swung the axe several times cleaving through the sisters of battle and genestealers that got in his path before reaching the closing blast door. He reached out and grabbed the door wedging his shoulder in beneath the door holding it up against the several tonns of pressure trying to close it while he waited for thorn and the rest to file through.
