On 19 January 1966, The Adjutant General of the U.S. Army in Vietnam published the first issuance of the United States Army in Vietnam Circular 210- 2, INSTALLATIONS Station List. From that date until 15 January 1973, more than 40 editions of this circular were issued. In simple columnar form, it listed all U.S. Army units operating in the Republic of Vietnam as of the publication date. Other elements of data included the operating units geographical location by local province, district or town, its next higher command and its APO number. The arrangement of these data elements allows easy establishment of command relationships. All units are listed in numerical order. Consequently, by alternating between the Unit and Next Higher Headquarters columns, the complete chain of command can be traced. Circular 210-2 was intended originally to meet administrative needs in mail and distribution. Its publication schedule was erratic and on a as needs basis as changes in the command structure dictated. An exhaustive search was made of the Vietnam War Collection of retired records held by the Washington National Records Center located 30 of the 41 known editions of USARV Circular 210-2. This compilation of U.S. Army combat units which served in the War of Vietnam is not complete it is intended only to be a preliminary list based on publications in use in the combat zones during the war. It should be used only as a point of departure for the military historians who, in time, will compile the complete official friendly order of battle.
