Vespin went flying down the long, narrow corridors of the large ship's various service hatches and air vents. It had taken a great deal of time to learn to properly read the extremely elaborate schematics that went along with Imperial naval craft. However, it was time well spent, as it allowed him to move at what many officers thought of as an almost supernatural pace. As it happened, and as with this case, that rarely proved to be a bad thing, when he was suddenly in need of an alibi somewhere else in the ship.

Before too long, he had found himself coming out on the upper-floor of the large armory. Here was stored the various heavy weapons platforms, ready to be lowered down into the waiting transports below as a moment's notice. His memory had served him well, as he was happy to find the room's layout had not been changed since his company had come on board.

Going across one of the many catwalks acting as the room's second floor, he couldn't help but grin when he found what he wanted. Using the pulley to tug it onto the metal of the walkway, it takes only a minute or so to get the tarp off and the hoists clear. Underneath was the autocannon that had been taking up so much space in the chimera he'd ridden aboard in. As soon as it was on level footing, he jumped behind the gun shield and slid the firing mechanism into its rarely used single-fire position.

Aiming down at the room's closest entrance to the brig further down, he waited. Cursing his luck for the lack of a proper scope on the large gun, he had only the sights to go off of, and just had to hope it was properly aligned. Just as he considered taking a single shot to get an idea of its accuracy, he looks down the barrel to see the first prisoner entering the room. Without warning, he lets fly with the first round, turning the man's head into smear along the floor behind him, with a rather large dent in the middle of the spray pattern.

The forward display had the effect he'd hoped for. Though all criminals, each had served at the least on their world's PDF. An autocannon was designed almost specifically for cutting swaths through hordes of infantrymen, and a choke point would mean their death if they were dumb enough to just rush in.

Luckily, a quick look told him the man he'd shot happened to have been heading to trial for shooting his squad mates. In the guard, that was unforgivable, even among penal legion troops. That meant he had a chance at talking with them, as no one would morn the man's death. Calling out across the room, he introduced himself, hoping to catch the ear of someone with a brain between their ears. "This is Vespin Longshank, Corporal of the Cadian 534th! I'll give you lads one chance to try and talk this out. I've got enough ammo and the right angle to take out all of you as soon as you pass that doorway. My men are hot on your tails, escorting a commissar with an even bigger stick up his ass than usual. You boys are gonna want to figure out terms with me, before you get pinched between me and my men, and I'm forced to hand command over. Send someone out with a white flag to talk terms. No flag, and whoever steps out gets a bullet between the eyes."
