The attached data identifies and summarizes the command and subordinate units that have been assigned or attached to the Direct Support Units, 1st Cavalry Division who participated, beginning with its functional organization and activation of specialized units during the Vietnam War. The introduction of the "Direct Support" concept allowed the 1st Cavalry Division Commander to have direct control over a broad range of operational specialization and capability in order to carry out its mission. In order to present a pictorial time line representation showing continuity of the commands of individual units, along with their designations (and redesignations), the data has been displayed in an indentured, structured format similar to the present day Line Organization.

In summary, the listing provides for an orderly, detailed presentation of the Order of Battle for the Direct Dupport Units, 1st Cavalry Division as originally activated in 1921 along with the incremental organizational changes that were made in the time interval up to the present day. The following paragraphs detail the method of presentation.

The period of activation of a command or unit is represented by a horizontal line starting with a numeric corresponding with the year of activation and ending with a numeric corresponding with year of deactivation or redesignation. Should the command or unit be reactivated in a later time period, the time line is reinitiated on the original reference line of entry at the location representative of the date reactivated. Subordinate units, listed under command units are listed with numeric designations in ordered sequence. An exception is made for those units which were reorganized and redesignated. This numeric of the year in which the redesignation took place is annotated by a tilde (~).

The data used in preparing this presentation was provided by the Center of Military History, Department of the Army. The certification to the accuracy of the assigned units and time line intervals will be conducted by a detailed analysis of the lineage sheets for each unit. Upon confirmation of unit and assignment/deactivation date, the entry will be annotated by the addition of the referenced Day/Month code. It is intended that this document will be a reference tool for future historical research activity. As such, when any errors or omissions are detected in detailed follow-on work, the document will be corrected and reissued.
