LandWarNet (LWN) is the United States Army’s contribution to the Global Information Grid (GIG) that consists of all globally interconnected, end-to-end set of Army information capabilities, associated processes, and personnel for collecting, processing, storing, disseminating, and managing information on demand supporting warfighters, policy makers, and support personnel. It includes all Army (owned and leased) and leveraged Department of Defense (DOD)/Joint communications and computing systems and services, software (including applications), data security services, and other associated services. LandWarNet exists to enable the warfighter through Mission Command, previously described as Battle Command. Other U.S. service equivalent efforts to LandWarNet include the Navy's "FORCEnet" and the Air Force's "C2 Constellation."
