Corporate Sector Security Division

The Security Division of the Corporate Sector Authority was responsible for law enforcement and the defense of the CSA's territories. The police of the CSA, known as Espos, had a reputation for brutality. Many of those convicted of political crimes within the Sector were sentenced to terms at a secret prison called Stars' End.

The Security Division also maintained a large fleet but of relatively outdated vessels to patrol their territory. Most of the fleet consisted of first-generation Victory-I-class Star Destroyers, Invincible-class Dreadnaughts, secondhand Recusant-class light destroyers and Marauder-class corvettes. The Authority IRD was one of the numerous types of starfighters used by the Security Division, as was the former CIS Mankvim-814 light interceptor. The CSA began purchasing large amounts of Dreadnaught-class heavy cruisers as soon as they were developed. At some point prior to the Battle of Yavin, the CSA military sold a number of its older Marauder cruisers to the fledgling Rebel Alliance.
