There are two books on the war in Laos worth reading:
Shadow War by Conroy:
https://www.amazon.com/Shadow-War-CIAs-Secret-Laos/dp/1581605358And better
Undercover Armies by the CIA's historian Jack Ahern. I've read the classified version which will blow you away. The version you can get will have a lot of black marks in it.
https://www.cia.gov/library/readingroom/docs/6_UNDERCOVER_ARMIES.pdfI have a deep suspicion of any other version of this history because the historian often has an agenda which effects his scholarship. I knew a lot of guys involved in that war in Laos....Operation "White Star" was 7th SFG involvement there. In the end, about 250 American para-military led 60,000 armed mountaineers in an amazing stand against the regular North Vietnamese Army...talk about force multipliers.
