After the the destruction of the Death Star, Arhul Narra, Wedge Antilles, and Luke Skywalker founded Rogue Squadron out of the veteran Red Squadron. They participated in many key battles of the Galactic Civil War like the Battle of Hoth and the Battle of Endor.
Rogue Squadron consists of five T-65 X-Wing Starfighters that are harder hitting and more durable than a regular X-Wing unit. They are useful versus other fighters and have a Lucky Shot that can disable one hard point on a large ship or station.
Rogue Squadron is a Forces of Corruption DLC unit. Now that Luke is a land hero, he is not present with the unit.
