The Joint General Staff (JGS) was the South Vietnamese equivalent of the U.S. Joint Chiefs of Staff (JCS). JGS headquarters were in Saigon. The major
difference between the JGS and the JCS was that the JGS had direct operational control over the South Vietnamese forces. United States commanders
of the Military Assistance Command, Vietnam (MACV), particularly Generals William Westmoreland and Creighton Abrams, cooperated closely with, but
did not control, the JGS.
