==History== Following the initial landing of Marines in South Vietnam on 8 March 1965, the 9th Marine Expeditionary Brigade (9th MEB) established their headquarters in an old French Army compound on the western edge of Da Nang Air Base. The III Marine Amphibious Force (III MAF) succeeded the 9th MEB and took over the compound.<ref name=Solis>{{cite book|last=Solis|first=Gary|title=Marines And Military Law In Vietnam: Trial By Fire|publisher=History and Museums Division, United States Marine Corps|year=1989|isbn=9781494297602|url=https://www.marines.mil/Portals/59/Publications/Marines%20and%20Military%20Law%20in%20Vietnam_Trial%20by%20Fire%20%20PCN%2019000310600_1.PDF|pages=15–8}}</ref><ref name=Kelley>{{cite book|last=Kelley|first=Michael|title=Where we were in Vietnam|publisher=Hellgate Press|year=2002|isbn=978-1555716257|page=5-250}}</ref>
