Am not sure if you are a reader.., there is a paperback by Keith William Nolan..called "Into Laos"...operation Dewey Canyon-2.
You will not be able to put this book down...and you will twist while reading it.
I am amazed at the fortitude and bravery so many sections of the U.S. armed services showed assisting the ARVN in this op in 1971.
Nearly 50% of the AVRN were killed or wounded ....and the book reveals the true nature of the ARVN and its different units and commanders..some fought to a man and were slaughtered on firebase hilltops when overrun....others sat in their tanks several hundred yards away..and smoked cigs while the lot got massacred.
On GI was on a helo...got shot down over the firebase in Laos..stayed to direct Phantoms and other airstrikes...went to the skids 2 days later...last man out type thing..and was shot down minutes later...now he was stranded on the adjacent fire base hilltop a mile away...and under fire almost immediatly.
Second hand book stores should have this paperback.
