A growing array of ground, surface, and air platforms with Tactical Data Link (TDL) capabilities account for ever-greater demand for TDL interoperability training for joint, allied, and coalition forces. The TDLs forming the Multi-TDL Network (MTN) have improved situational awareness concurrently with reducing targeting and decisionmaking timelines for maritime and aviation component commanders and aircrews and, more recently, tactical air control players. Examining the concepts and technologies and their applications leading to today's TDL and MTN capabilities will help planners and practitioners get a handle on interoperability issues and training needs, invaluable as technological advances enhance weapons range and mobility, decrease the time to detect and decide, and lead toward real-time command and control from beyond the line of sight.
