# Unified Command Plan
**Status: stub — expand.**
The **Unified Command Plan (UCP)** is the classified-in-part presidential document that establishes the combatant commands, assigns each one its **mission** and — for the geographic commands — its **area of responsibility**, the slice of the globe it owns. It is signed by the **President**, reviewed at least every two years, and revised whenever the map of American strategic priorities changes.
The UCP is a quiet but powerful instrument: it is how a president can create, abolish, merge, or redraw a military command **without an act of Congress**. Every line on the [[Combatant Commands Map]] — which continent belongs to AFRICOM and which to CENTCOM, whether space or cyber rates its own four-star command, whether "Indo-Pacific" or "Pacific" names the theater — is a UCP decision, and therefore a political one.
## Recent changes
- **U.S. Space Command** was re-established as a combatant command by UCP change in 2019.
- **INDOPACOM → U.S. Pacific Command** — the June 2026 renaming dropped the "Indo," reversing the 2018 rebrand and downgrading the India-inclusive framing of the theater.
- Proposals to **merge AFRICOM into EUCOM**, or to fold SOUTHCOM and NORTHCOM into a single Americas command, surface periodically as cost-cutting or priority-shifting measures; each would be a UCP change.
