Astromech droids are a series of versatile utility robots generally used for the maintenance and repair of starships and related technology. These small droids are often equipped with a variety of tool-tipped appendages that are stowed in recessed compartments. The R2 unit is a popular example of an astromech droid.
Chopper was the resident droid of the Ghost, assisting the crew in everything from ship maintenance to combat -- even though he didn't always want to. After many years of repairs and patch jobs, Chopper had a beat-up, worn look that matched his sometimes cranky personality. Aesthetics aside, he was an essential part of this small rebel team, and ultimately, was loyal and heroic.
An Arquitens-class light cruiser, the Imperial light cruiser was a double threat, both powerful and fast. It was equipped with multiple quad laser turrets and double-barreled turbolaser batteries, as well as concussion missile launchers, while quicker and more maneuverable than a Star Destroyer. After the destruction of the Lothal communications tower, a light cruiser was used to capture and relay information from surface courier droids brought aboard.
Designed by Sienar Fleet Systems, the Sentinel-class shuttle was a larger-scale troop transport used by the Empire. Much like its cousin, the Lambda-class shuttle, these vehicles featured three wings in a triangular layout: a stationary center foil and two articulated flanking wings. Imperials used the shuttle for missions that spanned the galaxy, from a search for droids on Tatooine to conflicts with the Lothal rebels.
