2-1B surgical droid

The 2-1B surgical droid was a model of medical droid that was common throughout the galaxy during the Clone Wars and Galactic Civil War.

Description
Humanoid in appearance, all 2-1B series droids were equipped with encyclopedic memory banks. Their memory banks and modular limbs helped ensure that the droids gave the best course of medical treatment in any given medical situation. The droids also had stabilizing feet, hydraulic legs, vocabulators, hydraulics covered by a transparent shell, and some even had hypodermic injectors.

Notable units
The droid TB-2 was a 2-1B droid stationed on the G9 Rigger freighter Twilight during the Clone Wars. He was originally a hologram, but was eventually uploaded into a body and stationed on the Venator-class Star Destroyer Resolute.

Other notable 2-1Bs were used on worlds such as Naboo, Alderaan, and Coruscant. One droid became a bartender working at Chalmun's Cantina on Tatooine. Other notable droids were also stationed on the Resolute and the Kaliida Shoals Medical Center.

The Galactic Empire used millions of 2-1B droids throughout its territory. One such unit later broke free and came to be known as 2-1B Delta.

2-1B was another notable surgical droid. He served the Alliance to Restore the Republic, and operated on the Alliance Commander Luke Skywalker. The droid treated Skywalker with bacta after he was attacked by a Wampa, and was later personally requested by Skywalker to treat him again after Skywalker lost his hand to Darth Vader.

The 2-1B droid 2MED2 served the Resistance during the Cold war, and was assigned to help a team of Resistance fighters transport the First Order RA-7 protocol droid O-MR1, who was believed to know the location of Admiral Gial Ackbar, who had been captured by the First Order. On the way back to the Resistance base, the team's ship crashed on an unknown planet and the only survivors were 2MED2, O-MR1, the Protocol droid C-3PO, the Construction droid CO-34, and the two Security droids PZ-99 and VL-44. The group of droids worked together to get home, but along the way every droid except C-3PO and O-MR1 were destroyed by creatures native to the planet. 2MED2 was destroyed in an attack from a Can-cell.
