66 MM Non-Lethal Grenade: Human Effects Review

Abstract : The purpose of this report is to assess the target effectiveness and the risks of severe (unacceptable) injury to those individuals who are impacted by the 66mm Non-Lethal Grenades (NLG) submunitions or projectiles (specifically the XM99 and the XM98) from the data in the literature and experimental data collected during development of the system. The XM98 is a distraction grenade that uses a pyrotechnic charge for crowd control through auditory and visual stimuli. The XM99 is a blunt trauma grenade that uses a pyrotechnic charge to discharge 0.32 cal rubber balls and achieve cwwd control through audio, visual, and physical stimuli. (Submunition refers to one of the l25g canisters that comprise the 66mm NLG. Projectile refers to one of the 0.32 caliber, O.4g balls dispensed from the XM99 submunitiom) The 66mm NLG will be capable of being fired by all currently fielded 66mm grenade launchers, primarily the Light Vehicle Obscuration Smoke System (LVOSS) 66mm M7.
