I'll have to check those out. My first tour as an USAF TACP was with the US Army's 2nd Armored Cavalry Regiment. It was responsible for the US VII Corps section of the IGB and the West German/Czech border. Up in the US V Corps, the 11th Armored Cavalry Regiment covered the IGB.
Regarding the link for the US Archives publication, you can get that as a Kindle eBook from Amazon.
