Area of responsibility in the context of "Unified combatant command"

As of 2025, the United States Department of Defense operated 11 unified combatant command, also referred to as a combatant command (CCMD). These are joint military commands composed of units from two or more service branches, and conduct continuing missions. Each CCMD is the highest echelon of military commands, in order to optimize command and control of all forces, regardless of branch of service, during peace or war. CCMDs are organized either on a geographical basis (known as an "area of responsibility", AOR) or on a functional basis, e.g., special operations, force projection, transport, and cybersecurity. Currently, seven CCMDs are geographical, and four are functional. CCMDs have specific badges denoting their affiliation.

The Unified Command Plan (UCP) establishes the missions, command responsibilities, and geographic areas of responsibility of the CCMDs. Each time the UCP is updated, the organizations are reviewed for efficiency, efficacy, and alignment with national policy.

A theater command (战区) is a multi-service formation of China's People's Liberation Army subordinated to the Central Military Commission. Theater commands are broadly responsible for strategy, plans, tactics, and policy specific to their assigned area of responsibility. In wartime, they will likely have full control of subordinate units; in peacetime, units also report to their service headquarters. The services retain administrative and "constructive" control. There are 5 theater commands: Eastern, Southern, Western, Northern, and Central theater commands, organized by a geographical basis.

The Eastern Theater Command (Chinese: 东部战区; pinyin: Dōngbù zhànqū) is one of the five theater commands of the People's Liberation Army (PLA), founded 1 February 2016. It replaced the Nanjing Military Region. The command is headquartered in Nanjing.

Its jurisdiction includes the provinces of Anhui, Fujian, Jiangsu, Jiangxi, and Zhejiang, as well as Shanghai and the East China Sea to include the Taiwan Strait. The Eastern Theater Command is primarily composed three subordinate single-service component commands: the Eastern Theater Ground Force of the PLAGF, the East Sea Fleet of the PLAN, and the Eastern Theater Command Air Force of the PLAAF which conduct combat operations within the command's area of responsibility. Also under the Eastern Theater Command is the Wuxi Joint Logistics Support Center (JSLC) of the CMC's Joint Logistics Support Force which provides logistic and material support to the command and Base 61 of the PLARF which is responsible for missile employment in the Eastern Theater.

The United States Central Command (USCENTCOM or CENTCOM) is one of the eleven unified combatant commands of the U.S. Department of Defense. It was established in 1983, taking over the previous responsibilities of the Rapid Deployment Joint Task Force (RDJTF).

Its area of responsibility (AOR) includes the Middle East (including Egypt in Africa), Central Asia and parts of South Asia. The command has been the main American presence in many military operations, including the Persian Gulf War's Operation Desert Storm in 1991, the war in Afghanistan, as well as the Iraq War from 2003 to 2011. As of 2015, CENTCOM forces were deployed primarily in Afghanistan under the auspices of Operation Freedom's Sentinel, which was itself part of NATO's Resolute Support Mission (from 2015 to 2021), and in Iraq and Syria as part of Operation Inherent Resolve since 2014 in supporting and advise-and-assist roles.

Amir Abdullah Khan Niazi HJ & Bar SPk SK MC (1915 – 2004), commonly known as General Niazi, was a Pakistani military officer. During the Bangladesh War of Independence and the Indo-Pakistani War of 1971, he commanded the Pakistani Eastern Command in East Pakistan (now Bangladesh). He signed the instrument of surrender as on 16 December 1971, his forces had to surrender to the Indian Army's Eastern Command's commander Lieutenant General Jagjit Singh Aurora by the order of the then President of Pakistan Yahya Khan.

Niazi's area of responsibility comprised the defense of East Pakistan from India during the war in 1971. His surrender in Dhaka effectively ended the war. The result was an Indian victory as well as the independence of Bangladesh.

The Commander-in-Chief, China, was the admiral in command of what was usually known as the China Station, at once both a British Royal Navy naval formation and its admiral in command. It was created in 1865 and deactivated in 1941.

From 1831 to 1865, the East Indies Station and the China Station were a single command known as the East Indies and China Station. The China Station, established in 1865, had as its area of responsibility the coasts of China and its navigable rivers, the western part of the Pacific Ocean, and the waters around the Dutch East Indies. The navy often co-operated with British commercial interests in this area.
