In February 1946, Brown was posted to the Operations Division of the Air Training Command at Barksdale Field, Louisiana, where he served under Major General Alvin C. Kincaid and his Assistant Chief of Staff for Operations, Brigadier General Thomas C. Darcy.
For the first time, Brown received a mediocre effectiveness report.
In December 1946 he joined Headquarters Air Defense Command at Mitchel Field, New York, as assistant to Air Chief of Staff, Operations, and later as chief of its ROTC branch.
On 1 July 1947 he became assistant deputy for operations.

Brown became commander of the 62d Troop Carrier Group at McChord Air Force Base, Washington, on 17 July 1950.
This group operated Douglas C-124 Globemaster II and Fairchild C-119 Flying Boxcar aircraft between the West Coast and Japan.
With the outbreak of the Korean War in June 1950, this mission acquired great importance.
In July 1951 he assumed command of the 56th Fighter Interceptor Wing at Selfridge Air Force Base, Michigan, part of the Air Defense Command, although he had never flown fighters before.
He learned to fly the Lockheed T-33 Shooting Star, North American F-86 Sabre and Lockheed F-94 Starfire.
On 1 January 1952 Brown became Assistant Director of Operations of the Fifth Air Force in South Korea.
He became Director on 15 July 1952.


Brown returned to the United States where he assumed command of the 3525th Pilot Training Wing at Williams Air Force Base, Arizona, on 6 June 1953.
He entered the National War College in August 1956.
It was the first and only service school he attended after graduating from West Point.
After graduation in June 1957, he served as executive to the Chief of Staff of the United States Air Force, General Thomas D. White.
Brown was promoted to brigadier general in August 1959.
He was selected to be military assistant to the Deputy Secretary of Defense, Thomas S. Gates Jr., and then to the new Secretary of Defense, Robert MacNamara, with the rank of major general.


Brown became commander of the Eastern Transport Air Force at McGuire Air Force Base, New Jersey, in August 1963.
In September 1964, he was selected to organize and command Joint Task Force 2, a Joint Chiefs of Staff unit formed at Sandia Base, New Mexico, to the test weapon systems of all the military services in order to avoid wasteful duplication of effort.
It was staffed by personnel of all three services.
In May 1966 he became the Assistant to the Chairman of the Joint Chiefs of Staff, General Earle G. Wheeler, on the recommendation of his predecessor in the role, Lieutenant General Andrew Goodpaster.
Brown was promoted to the same rank on 1 August 1966.
The preoccupation of the Joint Chiefs at this time was the Vietnam War, but he was also involved in the handling of the Pueblo crisis.


On 1 August 1968, Brown assumed command of the Seventh Air Force and also became deputy commander for air operations, U.S. Military Assistance Command Vietnam (MACV), with the rank of general.
As Seventh Air Force commander, he was responsible for all Air Force combat air strike, air support and air defense operations in Southeast Asia.
In his MACV position, he advised on all matters pertaining to tactical air support and coordinated the Republic of Vietnam and United States air operations in the MACV area of responsibility.
According to Goodpaster, Brown and MACV commander General Creighton Abrams "were like two brothers".
General George F. Keegan felt that:
[Brown's] relationship with General Abrams was the finest between a ground theater commander and his air subordinate that I have seen since 1941.
There was complete trust, rapport, an end to gamesmanship between one service and another.
It was clear from the outset that Abrams understood finally that in George Brown he had a personal friend whose life and resources were wholly committed to fulfilling the theater job and responsibility that Abrams had upon his shoulders.

Brown's tour of Vietnam ended in September 1970, and he became Commander, Air Force Systems Command, with headquarters at Andrews Air Force Base, Maryland.
