The Sentinel represented a repulsorcraft mech design produced and operated by the Wookiees residing on Kashyyyk. Its armament consisted of a light laser cannon, affixed to an arm extending from the cockpit area.
While the Sentinel vehicle excelled at breaking up infantry groups, its effectiveness diminished considerably when facing heavily armored vehicles like the AT-ST. Its speed also allowed it to perform reconnaissance duties. Enhanced models of this vehicle were designated as Heavy Sentinels. Sentinel (top) and Heavy Sentinel (bottom) seen in-game.
