A Unified Combatant Command (UCC) is a United States joint military command composed of forces from two or more services, has a broad and continuing mission, and is organized either on a geographical basis (known as "Area Of Responsibility", AOR) or on a functional basis. All UCCs are commanded by either a four star general or admiral and are considered "joint" commands with specific badges denoting their affiliation. UCCs (formerly known as "COCOMs", a term now reserved exclusively for the authority they hold, which is also called "combatant command") are led by Combatant Commanders (CCDRs), formerly known as a regional "Commander-in Chief" (CINC; pronounced "Sink").
