United States Navy In the United States Navy, task forces are generally temporary organizations composed of particular ships, aircraft, submarines, military land forces, or shore service units, assigned to fulfill certain missions. The emphasis is placed on the individual commander of the unit, and references to "Commander, Task Force" ("CTF") are common. A task force may be made up of several Task Units, sometimes nicknamed "Taffy", as in "Taffy 3" of Task Force 77, formally Task Unit 77.4.3. Designation The first digit of a task force designation is that of its parent fleet while the second is sequential.  Task groups within a force are numbered by an additional digit separated from the TF number by a decimal point. Task units within a group are indicated by an additional decimal. For example, "the third task unit of the fifth task group of the second task force of the Sixth Fleet would be numbered 62.5.3." This system extends further to task elements, individual ships in a task group. This arrangement was typically abbreviated, so references like TF 11 are commonly seen.Group. GlobalSecurity.org.

There is no requirement for uniqueness over time (e.g., the United States Seventh Fleet used TF 76 in World War II, and off Vietnam, and continued to use TF 70–79 numberings throughout the rest of the twentieth century, and up to 2012).
