Sky Corps

The Sky Corps was the military group of clone jet troopers established during the Clone Wars to serve in the Grand Army of the Republic. These specially-trained troops wore jetpacks for aerial operations and combat and carried compact DC-15 blasters.

Behind the scenes
Although not in Revenge of the Sith, a Sky Corps figure (based on concept art) was made for the action figure line, which later inspired the picture from Star Wars Insider.
