I don't know if they really are calling it Taskforce Black or if that is just a "media" name. Taskforce Black is already designated to another unit.
TF-88 was changed to Taskforce Orange and is still termed that (That's not classified, I know someone in training for it).
I thought Orange was all SIGINT stuff? TF-Green, Orange and Blue made up the other elements with CAG, DEVGRU, SEAL's, Ranger Batt, the 160th and the CIA's SAD or Special Activities Division just to name a few. I'm sure their OOB has changed a lot.
