The difficulty of moving injured soldiers to safety during battle has long been a problem for army commanders. In order to alleviate the stresses already placed on normal troop transports, the Wookiees of Kashyyyk modified an existing vehicle and created the Kettrifee Air Mover (KAM) solely as a medical transport.
The KAM, only sporting a single heavy blaster for defense, is swift compared to the bulky troop barges used by most armed forces in the galaxy. Its speed allows medical personnel to hop quickly in and out of battle in order to save as many lives as possible. The main vulnerability of the vehicle is the fact that it is entirely dependent on a single engine for propulsion; one well-placed blast can easily disable it. Another distinct characteristic of the KAM is the unique asymmetric design of the craft, a direct result of the peculiar aesthetics of the Wookiees.
