These “air defense systems” (also called “air and missile defense” (AMD) systems) provide surveillance, tracking, command and control, and weapons delivery capabilities to battlefield commanders. Historically, AMD systems were independently operated and managed by each military service. Gradually, they became more connected, and today several of these systems can communicate and operate collectively. This is basis for the concept of an integrated air defense system, or IADS. According to the Department of Defense (DOD), an “IADS is not a formal system in itself, but the aggregate of Service / functional component and agency AMD systems.” Considered part of what DOD terms “defensive counterair” (DCA), an IADS purpose is to protect military assets and vital locations from aerial threats. Conversely, countering an enemys IADS by destroying, suppressing, or otherwise neutralizing their system is part
