R. Azar was a Human male who served as a Military Assault Command Operations soldier during the mid-22nd century. In 2153, Azar was assigned as part of the MACO detachment aboard the Template:ShipClass starship, Enterprise for the mission into the Delphic Expanse. After Enterprise returned to Earth in 2154, Azar remained aboard as part of the MACO Detachment.
Azar stood guard in cargo bay 2 while Captain Archer attempted to glean information from Degra in a simulation. When Degra discovered the ruse, Azar boarded the simulator after Degra attacked the captain, and escorted the prisoner back to the brig. (ENT: "Stratagem")
In 2154, Azar helped Captain Archer to carry technology into a shuttlepod and guarded him. Archer, under the influence of the Xindi-Insectoids, ordered the MACOs to take over control of Enterprise and arrested some of his senior staff. Azar later guarded the bridge. (ENT: "Hatchery")
On February 13, 2154, Lieutenant Malcolm Reed asked the MACOs for volunteers to join the mission to board the Xindi superweapon. All the MACOs volunteered, including Azar, so Reed chose M. Romero, M. Forbes and W. Woods. Azar later assisted in the transport of supplements to the shuttlepod. (ENT: "Countdown")
Azar also accompanied Captain Archer to the quarters of the Tellarite ambassadors on board the ship when the Andorians under the command of Shran tried to kill them. The MACO force and Archer were able to stop the Andorians and arrested them after Talas was shot by Gral. (ENT: "Babel One")
R. Azar was played by regular background actor Jorge Benevides and by extra Chase Kim in two episodes. Another actor, Jack Nolan, also wore the uniform with the R. Azar name tag. The costume was sold off on the It's A Wrap! sale and auction on eBay for US$1025.00 and also included a name tag of Shawn Crowder.
