Greenie

"Greenies" was a nickname the Galactic Empire gave to one of the species native to the planet of Mimban. Although they did not take part in the insurgency, unlike the red-skinned Mimbanese, the Imperials regarded them as thieves, and suspected them of conducting reconnaissance for insurgents. Therefore, they were not allowed in Imperial camps unescorted.
