The Family of Weapon Sights – Crew Served (FWS-CS) will mount to the M240 Medium Machine Gun, the M2 .50-Caliber Machine Gun and the MK19 Grenade Machine Gun and will provide the Soldier with High-Definition (HD) infrared (thermal) imagery in all weather conditions, under all lighting conditions and through obscurants. The FWS-CS will also integrate an HD day camera, a laser rangefinder and a wireless Helmet Mounted Display (HMD).


The FWS-CS HD thermal sensor and HD day camera will provide Soldiers with a long-range capability for crew-served weapons. The FWS-CS integrated laser rangefinder will support a ballistic crosshair that shifts based on the target range, enabling Soldiers to get first bursts on target. The FWS-CS wireless HMD allows the Soldier to receive weapon sight imagery while behind protective armor and when using a weapon system with the Objective Gunners Protection Kit.
