Nomads

The Nomads are tricksters who live aboard trading vessels which travel through between the various colonized areas of the galaxy. Due to the prolonged periods of time spent about their ships, they have become accustomed to genetic mutation and mutation as normal processes. They toy with technology and biolody to enhance their chances during battle - using spotter drones to locate targets for other units, allowing them to eliminate whole enemy forces in one barrage before the enemy is even aware of the Nomad presence.
