MUQ-751 was a fourth-degree OOM command battle droid, a droid model under the OOM-series of battle droids, who was manufactured by the Baktoid Combat Automata to serve in the droid army of the galactic company known as the Trade Federation. MUQ-751 fought in the army as a commander sometime before the Clone Wars between the Galactic Republic and the Confederacy of Independent Systems, in which the Federation was a member, in 22 BBY. As with all OOM battle droids, MUQ-751 was 1.91 meters tall, had masculine programming and wielded an E-5 blaster rifle. The droid's head and some other parts of his body were colored white, while the rest was brown.
