The Integrated Sight (IS) is a Technology Demonstration program within the Force XXI Land Warrior Program. Like the other Force XXI Land Warrior components, the IS is a candidate for future technology insertion into the Land Warrior (LW) program. The IS integrates an uncooled thermal imager, eye- safe laser rangefinder, electronic compass, CCD camera and infrared laser pointer into a single lightweight sight. It can mount on weapons or be used in a handheld or tripod mode. The functionality of the IS provides the fighting soldier with the ability to acquire targets during daylight, darkness, adverse weather, and through battlefield obscurants to provide target position data (azimuth and range) for indirect fire. Standardized interfaces enable digital target location data and imagery to be transmitted to and from the LW computer/radio subsystem (CRS). By integrating the sensors into a single unit, the IS offers reductions in weight, power, and size which is expected to improve the LW soldier's fightability. The impact of sensor integration on the LW soldier's tasks will be evaluated during Force XXI Land Warrior testing. The IS is being developed jointly by Raytheon Texas Instruments Systems (RTIS), the U.S. Army CECOM RDEC Night Vision and Electronic Sensors Directorate, and the U.S. Army Soldier Systems command. This paper provides a comparative assessment of the IS and the LW baseline Weapon Subsystem, and outlines the expected improvements that the IS provides the fighting soldier.
