Back to my fictional world of Terrea
This is a standard patrol unit of the Gendoran Defense Air Force, often armed with medium caliber rifles to better damage vehicle threats to the air bases they're guarding.
The Gendoran Armed Forces is split into two theaters: Defense Force & Expeditionary Force. The Defense Forces is the only theater to have dedicated ground forces, while the Expeditionary Force consists of marines from its Navy for its ground units. The Defense Air Force is sworn to defend the nation's air space.
