An intermediate-force weapon often carried by law enforcement and security professionals, used to gain control over assaultive subjects. The expandable baton typically comprises a cylindrical shaft that contains telescoping metal pieces that lock into each other when expanded, and a solid metal tip at the end of the extended shaft. When swung, the extended baton can cause substantial damage because of the high kinetic energy imparted by its solid metal tip upon striking a surface. Most strikes are done on large muscle areas of the subject to avoid permanent injury. (wiki)

A typically non-lethal weapon, the telescopic baton is used as a secondary weapon by MBI agents when taser passification has failed. The weapon has been most often seen in the use of Agent McGrath, who has demonstrated a preference and uncanny ability to use the weapon in situations where a firearm would be advised. Agents are advised not to emulate this type of behavior.
