The Historian (TS-SCI Clearance) will support the Defense POW/MIA Accounting Agency (DPAA) to provide the fullest possible accounting for missing US service members from past conflicts. During the Vietnam War, Special Forces operators – working under the designation of Military Assistance Command, Vietnam – Studies and Observations Group (MACV-SOG) – documented their activities in post-mission After Action Reports (AARs). Most of these documents are still marked as classified Top Secret/Sensitive Compartmented Information (TS/SCI). These documents provide the most comprehensive record of special operations activities in Southeast Asia and include the date-time group and coordinates of each Special Forces insertion, extraction, and significant contact/observation throughout the Vietnam War. It is imperative that the Historian review, enhance, and make available these Top-Secret records to DPAA researchers to achieve their noble mission.
