We were fighting on the wrong side, of a war we couldn't win. And that was the good news.
The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492.

The human soldiers stranded on the planet Paradise have been recruited into an Alien Legion, to do the dirty jobs that the high-tech species won't do. Their first mission is to kick the enemy off a backwater planet no one cares about. It's a simple assignment, except everyone has a hidden agenda, and the planet could become a deathtrap.
After the renegade mission by the crew of the starship Flying Dutchman, the UN Expeditionary Force thought Earth was safe for hundreds of years, at least. Then, there was trouble on the homefront, and the President had to authorize a nuclear strike on Dayton Ohio. UNEF decided they did need the Merry Band of Pirates again, so the Flying Dutchman is sent out on a simple recon mission. But for the Pirates, nothing is ever simple, and their mission will become Armageddon.
