Callus Brutus had his target in his sights, the officer of these stormtroopers, seeing the autocannon of the Alpha Legionnaire cutting apart the stormtrooper who wielded the same weapon. Triggering the weapon, the heavy bolter spit out a hail of roaring death, which gave the officer no chance to act or even give an order, being blown apart by the exploding bolt rounds that flew out of the barrel of the heavy weapon, which pleased the plague marine, who was content to ignore the assault that the Alpha Legionnaire made on the stormtroopers now trapped between them, since he had more than a few problems of his own to worry about. One being the blinding flash that now left the traitor marine unable to see, which, while crippling, was not as dangerous as one might think, as this plague marine could fight without seeing, he just had to get close enough to land true blows with his own knife, which would indeed cripple the fools, one at a time with the gifts of Papa Nurgle.

Knife in hand, Callus Brutus charged as fast as a plague marine might go, which wasn't terribly fast granted, appearing more a walk of a being that would not be easily stopped. He heard the warp tear a gaping hole in the ship, and knew that the Alpha Legionnaire had died, claimed by whatever god he had chosen to follow into this place. Of course, between recovering from the blind grenade, and his own slow, pondering strides, he failed to see his own doom planted in the ground as he turned on the stormtroopers. The tripwire gave quickly, and the melta charge went off without delay, vaporizing the Plague Marine clean through his armor and leaving nothing behind, eerily reminiscent of how the other traitor marine had gone, but through entirely different means, of course.
