The BR-23 Courier is an obsolete, but durable personnel transport and courier ship that served in Old Republic fleets and militias. After finding the market for TIEs enormously more profitable due to the Empire's swift move away from transports like the BR-23, Sienar partially refitted its large back stock of BR-23s with civilian-grade systems and dumped them onto the open market. These inexpensive craft which are easy to repair proved to be boon of profit for Sienar.

    While most of Sienar's surplus stock found its way into the freighter market, the BR-23 has also seen use in cut-rate shuttle services and employment as personal skiffs. After leaving military service years ago, the BR-23 has proven to be popular among courier services, small-time shipping agents, and a good number of smugglers. In the case of the Rebels, they acquire these ships where ever they can find them as they can be easily re-converted back to their original troop transport duties. The Rebels' "Alliance Support Service" seldomly purchases these ships, as they prefer to steal BR-23s from who ever and where ever they are encountered.
