I was a USAF Combat Controller during the Vietnam war. This book gives a very brief history of Combat Controllers from WWII when they were called Pathfinders, to the present day. It is written for a young audience and focuses mainly on the duties for USAF Special Operations today. I bought this for my granddaughters so they could understand what grandpa did during the war. Please understand that this is a book written for the upper grades in elementary school. Grades 4 to 6 I believe. It was a good buy for the price and I am happy to share it with my grandchildren.
