4-42. The scientific and technical intelligence (S&TI) community also performs MASINT collection and processing primarily to support research and development programs and signature development. Every S&TI center has some involvement in MASINT collection or production that reflects that center's overall mission (for example, NGIC has responsibility for armored vehicles and artillery). Service research and development centers, such as the Communications-Electronics Command Research, Development, and Engineering Center, the Army Research Laboratory, and the Night Vision and Electronic Systems Laboratory, are also involved in developing sensor systems for collecting and processing MASINT. Elements within the Army Space and Missile Defense Command also exploit satellite-collected data for the purpose of MASINT exploitation. In addition to supporting the S&TI mission, INSCOM units also execute limited ground-based operational collection to support the ASCCs and subordinate units.
