R-19 paraglider
From Wookieepedia, the Star Wars wiki.
The Nen-Carvon R-19 Paraglider was developed for the Rebel Alliance Special Forces. Covered in reflec panels that baffled standard sensors, the gliders were excellent for infiltrating behind enemy lines. They were also equipped with low power transponders to allow troops to locate each other after landing.
Gunman, a member of the paramilitary unit Churhee's Riflemen, had experience with the gliders, likely through his unit's association with the Rebel Alliance.
