The raid on Balmorra by Rebel forces was another in a line of swift hit-and-run operations engineered by LieutenantKasan Moor, a Rebel sympathizer who defected from the Galactic Empire. Using her knowledge, Rogue Squadron led a successful string of victories against the Empire. Her knowledge of the Balmorra construction yard's layout and security systems allowed Rogue Squadron, led by Luke Skywalker, to get into the facility undetected.
Being a surprise attack, the battle was unorganized for the Galactic Empire. TIE Fighters were destroyed before they could take off, and Lambda-class shuttles were shot down during lift-off. The Empire couldn't launch a strong defense force. By the end of the raid, the Empire had lost an AT-AT factory and an AT-ST factory. As the battle was designed to be swift and cheap, and only three fighters were used, the flight quickly pulled out after destroying the two factories.
This was the second mission in Star Wars: Rogue Squadron where a T-47 airspeeder was used. The use of airspeeders during the battle is ambiguously canon, as the use of airspeeders in combat against Imperial walkers was canonically engineered by Luke Skywalker during the Battle of Hoth.
