warfare countermeasures; and intelligence dissemination. Additionally, I2WD provides engineering and management support to PEOs throughout the lifecycle of these systems. Night Vision and Electronic Sensors Directorate (NVESD) develops electro-optical electronic sensors, including thermal imagers, image intensifiers and lasers, to equip soldiers with imaging devices that aim to improve surveillance and targeting, safety, and lethality while providing increased capability for soldiers, ground/Airborne electro optics/infrared, force protection, and IED/mine and minefield detection. Product Realization Directorate (PRD) provides expertise in the areas of production engineering; manufacturing technology; maintenance concept engineering; quality assurance and continuous improvement; special manufacturing and quality assessment; reliability and risk assessment; industrial base technical advocacy and management; configuration management; technical data; specifications and standardization program management; technical project leadership; and technology acquisition planning and preparation for the Army communications-electronics community of practice. PRD influences design and system support during all phases of the product lifecycle, assisting in program synchronization, availability, improvement, fielding, delivery and sustainment of technology for the Warfighter. Space and Terrestrial Communications Directorate (S&TCD) aims to provide soldiers with adaptive, reliable battlefield communications with electronic counter-countermeasure capabilities and information security (INFOSEC). S&TCD performs research, development and engineering functions in terrestrial, avionics and space-dependent communications technology. Software Engineering Directorate (SED) provides software acquisition support and software engineering support to Army tactical systems throughout the systems' lifecycles, including concept and development, systems development and demonstration, production and deployment, and operations and maintenance. SED conceptualizes, develops and supports the fielding and sustaining of systems and software products, services and technologies that enhance Army, Joint and Coalition Force's war fighting capabilities. SED helps ensure America's Warfighters and Allies are equipped to defend the homeland and own the decisive edge throughout the battlespace. Product Director C4ISR and Network Modernization (PD C4ISR & NetMod) is an Army capital investment that provides a “test/assess-analyze-fix” environment that evaluates technical applications and maturity for emerging networking, sensors and C4ISR-enabling platforms on a year-round basis. Activities conducted at PD C4ISR & NetMod's laboratories or field sites are constructed as opportunities to expose systems to conditions not ordinarily available within their development environments. PD C4ISR & NetMod's integrated capabilities events inform the Army and joint communities on the capabilities of emerging technology. (NO LONGER EXISTS) CCDC C5ISR Center developed systems and projects TRACER is a mid-range, long wavelength synthetic aperture radar system that provides all-weather persistent surveillance. Rucksack Enhanced Portable Power System (REPPS) is a solar backpack system capable
