The "M1006" launches a solid foam "sponge grenade" at high enough velocity to wind someone or in extreme cases perhaps even break bones. The use of a softer foam sponge in the M1006 is likely a product of the serious injuries and fatalities caused by rubber and plastic batons in use by police forces around the world over the last few decades. The M1006 is still potentially lethal when fired at distances under 10 meters, having an 81-meter per second muzzle velocity, and is largely ineffective at distances over 50 meters.
