Which acronym refers to the multicast tactical digital information link used in Navy fleet communications (TADIL - J)?

• A. Battle Force Tactical Network (BFTN)
• B. Common Data Link (CDL)
• C. Multicast Tactical Digital Information Link (TADIL) -J (MTJ)
• D. Navy Cash

Answer: (C)

TADIL-J is a joint tactical datalink standard, and the multicast variant specifically carries the designation Multicast Tactical Digital Information Link - J. The question asks for the acronym that refers to the multicast version used in Navy fleet communications, and MTJ fits exactly: it stands for Multicast Tactical Digital Information Link - J, the multicast form of TADIL-J that distributes data to multiple recipients across the fleet. The other items are different systems or links not defined as the multicast TADIL-J: Battle Force Tactical Network is not a TADIL; Common Data Link is a separate data link used for unicast imagery links rather than fleet multicast communications; Navy Cash is unrelated to communications at all.
