The Common Remotely Operated Weapon Station (CROWS) is mounted on top of a HMMWV and controlled from a command center within the vehicle. This system can mount the M2 50-cal machine gun, the M240 medium machine gun, the MK19 automatic grenade launcher, and the M249 squad automatic weapon in addition to a powerful color day camera, an infrared camera, and a range finder. This system allows the gunner to sit within the armored vehicle and, using a computer screen, control the weapon with the use of a joystick. Prior experience with Xbox desired but not required.
