The Vietnam photograph collection (RG123s) deals exclusively with the Vietnam War from the U.S. involvement. It covers all aspects of the war and the various subjet matter is filed in boxes labeled according to subject. Althought the collection is large about one third deals specifically with photos of captured material and caches of material. Units are filed by division and then regiments, battalions or other lesser organizations within the division. There are several boxes of photos filed alphabetically by geographical name.
