Where can I find copies of the Weekly Intelligence Estimate Update (WIEU) reports prepared by J-2, MACV during the Vietnam War?

What you're looking for might be located in Record Group 472, Records of the United States Forces in Southeast Asia, 1950-1975. Here's a link of this record group in our catalog with all of the contact information for these records. I would suggest first contacting textual reference at College Park (archives2reference@nara.gov).

We haven't been able to locate any WIEUs here at Archives II, but there may be some at the The U.S. Army Military History Institute, The Army Heritage & Education Center, 950 Soldiers Drive, Carlisle, PA 17013. The website is USAHEC Home.
