Equipped with advanced power armor and a characteristically bad attitude, he was the bane of privates, chastising them for the slightest mishaps and breaches of protocol, especially if he didn't like them.
In-game, it is best to steer clear of him, as talking to him even while equipped with advanced power armor will end with him forcing the Chosen One to stand guard at the hangar. If initiated dialogue with him while being supposed to guard the hangar, he won't be pleased at all.
Should he spot the Chosen One out of Enclave armor, there is a chance he has them thrown off the base, thinking they are just another civilian. However, with enough points in primary and secondary statistics, one can fool him into believing that they have actually lost it or were not issued one by sloppy base personnel, resulting in a lengthy speech and a dismissal to the Quartermaster for another suit. Either way, you get armor.
