Trying to collect info on it, if anybody has any info on VBA in Vietnam please share.
It was Field tested by the 1st Cav Div between 15 January 1967 to 30 May 1967. Each soldier in the test who responded to the survey wore it a median of 25 times, with nobody wearing it more than 50 times. It was considered to heavy and too hot. (ACL-24/67I)
The 4th Infantry Division was scheduled to get Variable Body Armor on 30 November 1969, with the primary use being convoy duty due to its weight. I don't know if they ever did. (Senior Officer Debriefing Report MG Donn R. Pepke, C(G, 4th infantry Division, Period 30 Nov 68 to 14 Nov 69)
I have read a rumor that on 18 May the troops at Hamburger Hill were issued "extra heavy" flak vests. I assume this is Variable Body Armor and the troops are 3rd Brigade 101st Airborne. However, I don't know the source of this, or if it indeed was Variable Body Armor.
I have read that ~28,000 were sent to RVN but were not all worn, and shipments were canceled February 1970, but that has no source.
The only pictures I have seen of VBA in use are of the ROK
This soldier is par of the Capital "Tiger" Mechanized Division.
I am unsure what unit this soldier is from, but if I had to guess I suspect also Tiger Division.
I will reply with more pictures, I cannot fit anymore here due to file size limits.
