CROWS = Videogame + Vehicle + Real Guns
Most military vehicles can mount some sort of weapon, and even small protected vehicles like up-armored Hummers have top mounts. Manning them can be hazardous, however, as the story behind the Chavis Turret illustrates. Gunners are especially exposed to enemy sniper fire and counter-fire in urban environments, which figure prominently in current and expected war scenarios.
In response, larger armored vehicles have begun using Remote Weapon Systems (RWS), consisting of a gun and sensors that sit on top of the vehicle. These systems are controlled from inside via joystick and screen, and all ammunition, sensors, etc. are part of the topside assembly.
The USA's Common Remotely-Operated Weapons Station (CROWS) brings those capabilities to smaller vehicles, like up-armored Hummers or blast-resistant MRAPs. CROWS orders had traditionally been filled by Recon/Optical Inc., but a major "CROWS-II" framework agreement with Kongsberg in 2007 changed that landscape.

The CROWS System
This RWS approach does reduce situational awareness in many instances, thanks to a narrower field of view and fewer audio cues. In exchange, however, RWS systems offer full in-hull protection for the crew, much better fire-on-the-move capability, and the ability to use the RWS' advanced sensors in night or obscurement scenarios. RWS have become extremely popular in recent years; major competitors in this space now include BAE (LEMUR), Elbit Systems (ORCWS), Kongsberg (Protector), RAFAEL (RCWS and Samson families), Recon Optical (Raven), and Thales (SWARM).
CROWS is versatile and modular. It can mount weapons such as the M2 HB .50-cal Machine Gun, Mk19 40-mm Automatic Grenade Machine Gun, M240B 7.62-mm MG(Machine Gun) and M249 5.56-mm Squad Automatic Weapon.
The system's sensor unit includes a daylight video camera with digital video processing capabilities, a thermal imager for night operations, and an eyesafe laser rangefinder. It is furnished with a fully integrated fire control system that provides ballistic correction, and offers a 2-axis stabilized (azimuth and elevation) gunner-operated weapon system, that corrects for vehicle movement. The Recon/Optical mount is capable of continuous 360 degree azimuth rotation and -20 to +60 degree elevation; the Kongsberg mount shares these abilities, with a maximum slew rate of 100 degrees/second and a topside weight under 350 pounds.
The system's control group, which mounts inside the vehicle, is the gunner interface allowing operation within the vehicle's protective shell. Its main components include a display unit, Switch Panel Unit (SPU), and hand controller (joystick). The control group provides full remote control of the weapon system via on-screen menus presented on the display, and by the switches on the SPU and joystick.
The CROWS system has received excellent reviews from US troops in Iraq – and if this sounds like a video-game to you, you're in good company.
The US Army worked with game developers to put a CROWS module and mission sets into the new version of the hit Pentagon-sponsored videogame/ recruiting tool/ preparation tool "America's Army." That would certainly cut the time required to train new recruits. Indeed, the additional levels of proficiency possible through such approaches will act as another incentive for countries to equip their vehicles with RWS systems, instead of traditional gunner mounts.
In the US military, CROWS systems currently equip the M1114 up-armored HMMWVs (Armored Scouts/Military Police), and M1116 up-armored HMMWVs (U.S. Air Force); the M93A1P1 nuclear, biological, chemical reconnaissance vehicle, scout vehicle; and some of Textron's M1117 Guardian Armored Security Vehicles (Military Police), which also have their own armored turrets.
Feb 11/11: Kongsberg Defence in Kongsberg, Norway receives a $120.4 million firm-fixed-price time-and-materials contract that raises the maximum quantity of CROWS turrets from 10,349 units to 11,690 units.
Work will be performed in Johnstown, PA, with an estimated completion date of Aug 21/12. The original bid was solicited through the Internet, with 3 bids received by U.S. Army Contracting Command in Picatinny Arsenal, NJ (W15QKN-07-D-0018).
