The US Army M111 grenade marks the first major grenade upgrade in nearly 60 years since 1968. This new shockwave grenade changes urban warfare tactics. It uses blast overpressure instead of deadly shrapnel. That means fewer accidental injuries in tight spaces. The M111 grenade is built for indoor combat and room clearing missions. It delivers powerful pressure waves that damage internal organs instantly. Soldiers no longer depend only on fragmentation grenades like the M67. The US Army developed this weapon after lessons from Iraq war combat zones. Urban warfare needs precision and control. The M111 grenade reduces collateral damage risks while increasing effectiveness.
