If I wanted a character who was a boarding specialist would you consider him part of the Landers or the Navy? Although my character would be quite capable of taking control of systems of a ground base, he specializes in ship systems. Basically my character's favorite tactic is to reverse anti-gravity on ships, often multiple times, thereby knocking at least several crew personnel unconscious. Anyone (and anything) who is not strapped in or magnetized is going for a ride. Naturally he'd tell the rest of the landers to activate their magnetic boots or whatever they have.
