Sentry droids were droids that acted as sentries in various locations. In 2 BBY, multiple DT-series sentry droids were stationed on a class four container transport that drifted into a storm on Wynkahthu. The droids and the ship were destroyed during a skirmish with the Spectres, Hondo Ohnaka, and Azmorigan.
