The MIL-STD-6016, also known as the Tactical Data Link (TDL) 16 Message Standard, is a Department of Defense interoperability standard that governs the standardized set of Link-16 messages for DoD use. This document, previously known as TADIL J, JTIDS, or MIDS, is crucial in the defense and aerospace industries, particularly in systems that require secure and standardized communication protocols. The MIL-STD-6016C version of the document is unclassified and its distribution restriction has been lowered from “D” to “C”, making it accessible to federal government and its contractors. However, foreign disclosure of this standard still requires authorization. A common search question about this document might be "How can I obtain a copy of the MIL-STD-6016C?" Federal employees can get copies from ASSIST, while federal contractors can obtain it through their government POC who has access to ASSIST.
