USAS 1st Pursuit Group by Jon Guttman (2008, Paperback)

This book cuts through the literary fog of war that usually surrounds American military endeavors. I.e. it is a factual piece and not one that takes hollywood as its background. Also, there are not a great deal of literary works on WWI to be found. Yes, I know there are thousands but not like the modern era of WWII and greater. The author goes into great detail to examine the unit in question. Though I must say that this is a fact to be found in all Osprey Books.
