Marine Corps Systems Command started fielding thousands of suppressors to infantry, reconnaissance, and special operation units for employment on the M27, M4, and M4A1 rifles. Small arms suppressors are designed to reduce a weapon’s noise, flash, and recoil. “Our intent was to leverage commercially available technology to support the near-term modernization required for our close combat Marines,” said Billy Epperson, the Infantry Weapon Capabilities Integration Officer at CD&I. Other than the tactical advantages on the battlefield, the reduced noise of the suppressors also prevents any hearing damage for Marines.
