Note: The ominous, though nameless, figure here is correct of course: eventually the Orbit Guards do become the most important and numerous military force, outnumbering the SDF even in war-time. After The Exodi, land-based militaries were simply no longer required, and the amount of policing that had to be done in the orbit-space of each major planet and station was a massive undertaking, requiring thousands of men and women in hundreds of ships across the system. Without the Orbit Guard to keep piracy in check, there would have been very little trade or tourism throughout the system.
