Tactical Data Link


A Tactical Data Link (TDL) uses a data link standard in order to provide communication via radio waves or cable used by the U.S. armed forces and NATO nations. All military C3 systems use standardized TDL to transmit, relay and receive tactical data.

Multi-TDL Network (MTN) refers to the network of similar and dissimilar TDLs integrated through gateways, translators, and correlators to bring the air, land, and sea common tactical picture and/or common operational picture together.

The term Tactical Digital Information Link (TADIL) was obsolete (per DISA guidance) and is now more commonly seen as Tactical Data Link (TDL).
