visible, and MILES lasers, while the cameras provided a video feed and thermographic capabilities, plus allowing a soldier to shoot around corners or behind cover without actually exposing himself to enemy fire. This is highly effective for confirming kills without exposing one's position. Helmet The Helmet Subsystem (HSS) combined a lightweight advanced helmet with a computer and OLED display that provided various information from digital maps and troop locations down to his weapon-mounted video camera. This is what would have allowed the soldier to see (and fire) around corners. The HSS also incorporated a microphone as well as a headset. Armor and protection The Interceptor Body Armor system and Modular Lightweight Load-carrying Equipment (MOLLE) load-bearing system currently in service with the U.S. Army today are partially a result of the Land Warrior program. Computer The Computer Subsystem (CSS) provided the processing power and storage capacity for the system. The CSS is based around an ARM core processor. Prior to the project's cancellation (when project funds were moved to Hurricane Katrina relief) the computer used was Techsol's Ethernet Audio Interface board, powered by an s3c2410a processor from Samsung Semiconductor, featuring an ARM-920T core running at up to 200 MHz. The board included a low-power Ethernet interface using the cs8900a from Cirrus Logic, an audio interface using the internal IIS audio interface of the Samsung chip connected to an AKM integrated Audio Codec and Amplifier, a GPS receiver from Motorola, and using GPIOs for the push-buttons used for Volume UP/DOWN, and also Channel UP/DOWN. With a wide-voltage-range input power-supply, the entire wearable computer board was 2/3 the size of a business card (see photo). Future versions were powered by an XScale processor from Intel. The CSS connects to each one of the LRUs as well as to the batteries. Navigation The Navigation Subsystem (NSS) provided positional information, it integrates a GPS receiver and a Dead Reckoning Module (DRM) that maintains accurate location when GPS signal becomes unavailable. Radio The Communication Network Radio Subsystem (CNRS) provided communications capabilities for the Land Warrior. The CNRS is based on EPLRS. Software Land Warrior's software system was powered by a variant of the Linux operating system and has a modular, open architecture for further improvement. Reliability in recent testing at Fort Benning has been extremely high. The Land Warrior software suite contains six main software packages for weapon sights and for data.
