Looking for unit histories for the 1968-1974 for the 86th ARCOM which fell under the Fifth Army within the files below.
Record Group 319 - Office of the Chief of Military History
Unit Records, 1967-1971 [NAID #120942114, P 1686], 3 NA boxes
Dear Mr. Schneider,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled Unit Records, 1967-1971 in the Records of the Army Staff (Record Group 319) but we were unable to locate unit histories for the Fifth Army or the 86th ARCOM.
We hope this is helpful.
