Mulgrew huffed to himself as he approached the CIC, a bit late compared to everyone else if he didn't miss his guess. But that was hardly his fault, or so he would like to think. It wasn't as if he had been responsible for the obvious favoritism that had taken over the UNSC defense forces, favoring the Marines over the Army. Sure, the Marines had greater tactical flexibility, and general quality, but that didn't mean the Army was any less deserving. But it seemed that the politicians didn't agree.

Still, he tried to not let things like that cloud his view, especially as he prepared to take part in this operation. It would be a nice change from dodging snipers and dealing with Insurrectionist IED's, now wouldn't it? And he supposed that was the best he could ask for, in the era after the Human-Covenant War. 

The halls were bustling with activity, the ship preparing to get on the move for this mission even with the covert nature of it. It just meant that there wasn't any idle chit chat from those passing by, focused on their jobs as they were. A pity, but he'd survive. He was here after all. 

He made his way in at a brisk walk, entering the room before saluting. "Thomas Mulgrew, reporting for duty sir," he said firmly, as he had been trained to do. ONI spooks gave him the creeps, and he noted the Spartans, but maintained his composure. If nothing else, he would show them what the Army could do.
