Sky Corps
From Wookieepedia, the Star Wars wiki.
The Sky Corps was the unit of the Grand Army of the Republic composed of clone jet troopers.
These specially-trained troops wore advanced jetpacks for aerial operations and carried compact DC-15S blasters.
[edit] 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. There was also a LEGO version that was made to accompany the LEGO Turbo Tank set, based off of the Heavy Assault Vehicle/wheeled A6 Juggernaut.
