It was a BIG deal. The Outer-Orbital Legion was a legitimate mercenary organization, and a massive one at that. It took two years of active investigation by an international criminal investigation task-force to connect all the dots, as it were.

When the joint task force made their move, they were able to seize effectively all of the Legion's inner-system assets, it was everything else the Legion had scattered throughout the rest of star system that was the problem. When they realized what had happened, the Legion grabbed everything they had and ran like hell.

This is what resulted in the six month system wide fleet-hunt. The-Powers-That-Be mobilized every asset that they possibly could in order to capture the Legion. As a result, all the major powers had patrols and/or task forces hunting for the Legion. So while a lot of people were activated for the hunt, at most maybe a third of them actually saw any action.

As of 245 SA The Legion was no more. Any members who hadn't been caught were either doing their best slip back into regular society unnoticed or had become backwater pirates of little importance.

I think that fleshes out the details, any remaining questions?
