From UFStarfleet LCARS
Task forces have been set-up to easily coordinate and manage missions on a Fleet Level.
While there are permanent task forces established temporary task forces can be set up to facilitate extra missions that happen on a fleet level.
Permanent Task Forces
Permanent Task Forces do not have a Task Force Commander, all missions that are included in these Task Forces are under the advisement of the Chief of UF Starfleet Operations. In order for a ship/station to be recorded into these Task Forces they must open communication with the Office of the Chief of UF Starfleet Operations with the proposal for the mission outline.
Permanent Task Forces correlate into one major story line and are always ongoing with no end date.

Temporary Task Forces
