The IG-RM bodyguard and enforcer droid, more commonly known as the IG-RM thug droid and sometimes known as the IG-RM war droid, or IG-RM assassin droid, was a security droid model manufactured by Holowan Laboratories. They were commonly used as enforcers, and as such proved popular with gangsters. Cikatro Vizago, a crime lord on Lothal during the reign of the Galactic Empire, employed IG-RM thug droids to conduct his criminal operations. The Mining Guild also made use of these droids on ore crawlers.

Following Order 66, Kalleran smuggler Janus Kasmir and his friend, former Jedi Padawan, Caleb Dume, stole several of these from a warehouse in Plateau City on Kaller. Kasmir then used one to break Dume out of his cell.
Lothal smuggler and Broken Horn Syndicate crime lord, Cikatro Vizago, had several of these droids under his command to enforce his rule. Vizago could usually be seen with two IG-RMs in close proximity with a half-dozen others located nearby in case of trouble.
Cikatro Vizago used these droids to attack Ezra Bridger and the pirate Hondo Ohnaka, however, Ezra managed to steal the master control switch from Vizago to shut off the droids.
The Mining Guild employed these droids to serve as guards aboard their ore crawlers.
The design of the IG-RM thug droid was developed from an early piece of concept art developed for IG-88 by original trilogy concept artist Ralph McQuarrie.
