Task Force 20

This was part of the formal United States Military Communications-Electronic Board system. The other iteration was a much more temporary task force of the Joint Special Operations Command, one of the designations used by the JSOC high value targets task force which began its life as Task Force 11 (also doubling a U.S. Navy designation) after the September 11 terrorist attacks. Task Force 20 was a task force for the now-deactivated United States Second Fleet, as well as a now-inactive task force for the United States Fleet Forces Command. In its Second Fleet role, TF-20 served as that fleet's Battle Force. In its subsequent role in the Fleet Forces Command, TF-20 served in a training role for U.S. naval units preparing to deploy to the United States Sixth Fleet in the East Atlantic Ocean and Mediterranean Sea, as well as the United States Fifth Fleet in the Indian Ocean and the Persian Gulf. Task Force 20 was one of the task force designators assigned to the United States Fleet Forces Command in the Atlantic, and was previously one of the task force designators assigned to the United States Second Fleet. According to Norman Polmar, writing in Ships and Aircraft of the U.S. Fleet, the designator was reserved for the Second Fleet's Battle Force, and the commander of that force was to be Commander, Second Fleet. This was the documented case from 1978 to 1987, and from probably much earlier.
