Cancelled US Army program

Land Warrior was a United States Army program, launched in 1989, officially got its name in 1994, cancelled in 2007 but restarted in 2008, that used a combination of commercial, off the shelf technology (COTS) and current issue military gear and equipment designed to:
integrate small arms with high tech equipment;
provide communications and command and control at the infantry soldier level;
look at the individual infantry soldier as a complete unit rather than as a segment of a larger force. While technology had long been a primary focus of the U. S. Armed Forces, very little of it had actually been adopted by the U. S. Army infantry soldier. With growing concerns of urban warfare and dismounted infantry actions, the U. S. Army recognized the need to upgrade an individual infantryman. The Land Warrior program drew upon many wearable computer concepts, and maximized existing technologies to correct most infantry soldier limitations in the short term. The SI (Stryker Interoperable) version of the system completed U. S. Army testing as of November 2004. Due to limited resources, and issues with the overall weight of the system, Land Warrior was cancelled by the Army in February 2007, but restarted in July 2007. Despite the initial system's cancellation the 4th Stryker Brigade Combat Team (SBCT) was deployed to Iraq as part of the spring 2007 "surge" of U. S. forces, and used the Land Warrior, on which they had trained for the previous few years. The systems and technology of the Land Warrior program were to be rolled into the Future Force Warrior program, and the Army has developed the Nett Warrior system to supersede Land Warrior as its next soldier network program. Internationally, there are several similar development programs, these include IdZ (Germany), FIST (UK), Félin (France), Land 125 (Australia), MARKUS (Sweden), Soldato Futuro (Italy), IMESS (Switzerland), Projekt TYTAN (Poland), FINSAS (India) and ACMS (Singapore), Ratnik (Russia), SARV (Iran).

The original Land Warrior program, under a different name, was undertaken by General Electric in Moorestown, New Jersey in approximately 1989, as a prototype having intent to eventually reduce size and weight in future phases. Then in the mid 1990s, the name Land Warrior was adopted and the program was handled by a division of Hughes Aerospace, which was subsequently acquired by Raytheon. (The soldier radio component of Land Warrior was to be supplied by the Integrated Information Systems division of Motorola.) Early demonstration versions of the LW system used software written in the Ada programming language running on a Unix platform. In January 1999, under the direction of Bruce D. Jette, an attempt was made to reduce development costs and accelerate the program, and the development work was transitioned to a multi company team that had been organized by Exponent, Inc. (NASDAQ: EXPO), an engineering firm with headquarters in Silicon Valley. An intensive redesign of the system ensued, and both the embedded firmware and the application software were rewritten from scratch. Many of the COTS hardware components were purchased (literally "off the shelf") at Fry's Electronics, a Silicon Valley based retail chain. Approximately 100 proof of concept Land Warrior units were built and successfully demonstrated in September 2000 by a U. S. Army platoon that was air dropped into a large war fighting exercise at Fort Polk, Louisiana. These initial prototype units, designated Land Warrior v0.6, were built around a PC/104 computer platform running Microsoft Windows. The system used the CAN bus protocol on the wired PAN (personal area network). The communications subsystem was built using Windows CE running on a StrongARM platform, and the wireless network protocol was IEEE 802.11. During the Fort Polk exercise, preliminary interoperability with traditional military radio networks was also demonstrated for LW v0.6, using a two way, SINCGARS compatible gateway radio. The success of the Fort Polk exercise reinvigorated the program, and further funding was allocated for the next phase of LW development. A "Land Warrior Consortium" was formed by several of the contracting firms, with the goal of designing and building the first field able LW system, designated LW v1.0, later LW IC (Land Warrior – Initial Capability). The basic Windows and WinCE platforms were retained, and a new hybrid PAN was designed, which drew upon both USB and FireWire protocols. A modified version of the IEEE 802.11 protocol was adopted, which added various enhancements for COMSEC and information security, mobile ad hoc network (MANET) capabilities, and support for multi hop packet routing. In 2003, a variant of the LW IC system was developed to incorporate features of the CombatID System (CIDS) – a form of IFF (identification friend or foe) that is designed to reduce the potential for friendly fire incidents. This version, designated LW CIDS, was successfully demonstrated in interoperational tests with several other CIDS equipped units at Moffett Field, California. As the Land Warrior program matured, it became clear that its successful deployment would hinge significantly upon the key factor of batteries. The need to continuously resupply (or recharge) LW batteries was proving to be a major logistical challenge. This was one of the driving factors behind the decision to move away from an earlier plan to initially equip airborne Army units, as in the Fort Polk exercise, and to focus instead upon those using Stryker ground vehicle systems. This latter approach would enable more LW batteries to be distributed and/or recharged as needed. The contract for development of the Land Warrior – Stryker Interoperable (LW SI) version of the system was awarded in 2003 to an industry team that was led by General Dynamics The system successfully completed the assessment, which was based on Joint Capabilities Integration and Development System (JCIDS) guidance, and received testimonials from the unit. However, funding for further system development under the Land Warrior program was suspended in February 2007, although the 4–9 Infantry was deployed to Iraq and used the LW SI system extensively. The Land Warrior program was then re instated. This was the final trial phase before the key decision is made on the overall future of wearable soldier systems, including Future Force Warrior. The decision was made in 2011 to continue the program. 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.

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.

The Communication Network Radio Subsystem (CNRS) provided communications capabilities for the Land Warrior. The CNRS is based on EPLRS.

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.

Land Warrior was the first U. S. Army soldier network system to be used in combat since the networked soldier concept began in 1989. 229 Land Warrior ensembles were deployed by the 4th Battalion, 9th Infantry Regiment to Iraq from May 2007 to June 2008. A Stryker Brigade later deployed with the system to Afghanistan, and Land Warrior remained in use until spring 2012. The Army built upon Land Warrior with the Ground Soldier System (GSS) as its successor, an advanced dismounted soldier integrated situational awareness system that entered technology development in February 2009. GSS Increment 1 was renamed Nett Warrior in June 2010 after Medal of Honor recipient Robert B. Nett (although the term "Nett" has frequently been misinterpreted as a reflection of its tactical networking features). Nett Warrior was first demonstrated in spring 2011, which then was essentially the 10 pound Land Warrior ensemble with some enhanced additional software. Later iterations focused on a hand held solution that integrated a commercial hand held screen device with the Rifleman radio, simplifying the system and decreasing weight to Nett Warrior utilizes enhanced smartphones, using different models over the course of its development including the Motorola Atrix, Samsung Galaxy Note I, and the Samsung Galaxy Note 2.
