The US Marine Corps is developing the Modular Crowd Control Munition, a modified Claymore mine with 600 rubber balls replacing the more traditional steel pellets. The MCCM is to be used to keep rioting crowds away from peacekeepers, as it is non-lethal (except within 5m). It has a maximum effective range of 15 meters. So that Marines do not confuse it with the real Claymore, the back is lime green and has raised bumps so that it can be identified by sight or (in darkness) by feel.--Stephen V Cole
