The Mynkoma CP-3 is a pre-war electric baton, designed to be used by law enforcement personnel for non-lethal riot suppression and similar duties. It only gained moderate popularity among law enforcement personnel, generally being out-competed by other non-lethal solutions, but was enormously popular among criminals, gangsters, mercenaries, and pirates because it could be easily modified to deliver lethal shocks, yet would get through most scanners with minimal issues.

Due to similarities with Cerberus Shock Batons during the war, the CP-3 stunner and its post-war successors rapidly lost popularity among police. Today the CP-3 is unlikely to be wielded by anyone besides a criminal or mercenary.
