Top Definition
An intermediate-force weapon for law enforcement and security professionals, used to gain control over assaultive subjects. The baton is a cylindrical shaft that contains telescoping metal pieces that lock into each other when expanded. When swung, the extended baton can deal massive damage due to the kinetic energy emitted from its solid metal tip upon striking a surface. Most strikes are done on large muscle areas of the subject in order to avoid permanent injury. Expandable batons come in various sizes, including 16, 21, 26, and 31 inch when extended. Synonyms: telescope baton, extendable baton
