The Marine Corps is experimenting with new options for its unmanned, squad prototype vehicle, including rocket launchers and a remote weapon station armed with a .50-caliber machine gun.

The Marine Corps Warfighting Lab recently sent its Expeditionary Modular Autonomous Vehicle, or EMAV, to the Muscatatuck Urban Training Center in Indiana for a company of Marines to test in the dense urban terrain environment.

Marines tested one of the vehicles, equipped with a .50 cal. mounted on a Common Remotely Operated Weapon Station, or CROWS, to see how squads can benefit from having a heavy machine gun in their arsenal, Dave Stone, ground combat element robotics engineer for the Lab, told Military.com at the Modern Day Marine 2019 expo.
