The Dropship Pilot wasn't never mentioned to be part of the UNSC. It's likely Locus isn't working for UNSC as well, but another group. This is because when he contacts his allies, he calls them "control", not "command" like the Reds, Blues, or UNSC soldiers. It's likely he and his group were (partially) responsible for the spaceship to crash so they could take something from it and is preventing the Reds and Blues to contact the UNSC until he finds what he's looking for.

It's also possible that he and his group are the people who have stolen the PF equipment mentioned by Carolina in Don't Say It. This gives the chance that Carolina and Epsilon-Church will return at the end of the season.
