Eliminate The Pirate Campers (Guristas) (Level 3)

From Battleclinic.com

We've been flooded with reports recently of a group of Guristas pirates who've been ambushing passersby near planets in {System Name}. Some of the unfortunate souls who lost their ship or loot to these scoundrels were employed by some of our allies, and of course we are also partly responsible for maintaining law and order in these parts, so I want you to head over to XXXX and teach the goons a lesson they'll never forget. I trust it that you're up to the job, soldier?!
