Bouncing Betties' are a type of anti-personel floor mines for interior use that can be activated in an armed assault situation. They are seen in WEC facilities.
Bouncing Betties are concealed, spring-loaded mine flingers. Unlike the standard oncussion mines which are usually triggered by direct pressure immediately above them, Bouncing Betties can be deployed by a remote trigger, and when activated, they throw high-explosive micro-grenades in a pre-set radius. category;technology
