Polaris is preparing its Arctic kit for the MRZR Alpha as part of a deal with U.S. Special Operations Command to supply lightweight tactical all-terrain vehicles.
The .338 NM machine gun is lighter than the current M240 in 7.62mm but can shoot with some of the same effects as the .50 caliber, a much heavier platform.
The U.S. Army is looking for ways to rapidly buy lightweight precision munitions for unmanned aircraft systems as it burns through more expensive missiles carrying out a wide variety of missions.
