That's just for promotional reasons.Tucker represents the New Republic (as he's the most well-developed character out of the BGC with the Republic), and Locus represents the Federal Army.

Ironic becuase neither of them are actual members, with Tucker just being some guy who landed on this planet, and Locus being hired help. Though, that may have been the point with the "What do you fight for?" message.
