Trainees from the army and marines this week have been undergoing training in riot control and crowd dispersal. They’re getting the experience at a military police school at Fort Leonard Wood. The trainees are learning to use non-lethal weapons like munitions that fire rubber pellets. Organizers say the weapons and experience would most likely be used during overseas humanitarian missions where a local crowd is causing trouble. Army Colonel Bud Irish says the non-lethal tactics are in their infancy and are constantly evolving.
