The Coastal Defense Division represented a component within the Galactic Empire's Stormtrooper Corps, specifically a division. This trooper division was made up of coastal defender stormtroopers, whose duty was to provide defense for coastal regions, shorelines, and beaches of planets that possessed sizable maritime areas. A key difference from other specialized units in the Imperial Army's Stormtrooper Corps was that the Coastal Defense Division's shoretroopers didn't have to go through further training; any trooper was eligible for the unit because its role was temporary and recurring. The singular condition for stormtroopers wanting to be part of the division was holding the rank of sergeant, and they had to command squads of standard stormtroopers if combat occurred.
