I got the box set "Vietnam: America's Conflict" for my birthday last week and started watching it. It came from the bargain DVD bin at Walmart for $5. There's over 23 hours of footage and from what I've seen, there are a lot of US Army produced informational films from the 1960s including "The Big Picture" unit histories of the 1st ID, 9th ID, 101st AB, 1st CAV, 11th ACR, etc. in Vietnam. Includes films about the USMC, USAF, brown water navy; lots of great reference footage of units in theater.
