A Unified Combatant Command (UCC) is a United States joint military command that is composed of forces from two or more services and has a broad and continuing mission. These commands are established to provide effective command and control of U.S. military forces, regardless of branch of service, in peace and war. They are organized either on a geographical basis (known as "Area of Responsibility", AOR) or on a functional basis. Each UCC is commanded by a combatant commander (CCDR), who is a four-star general or admiral. UCCs are "joint" commands with specific badges denoting their affiliation. - Source: Wikipedia
