I have this book and consider it part of the "threefer" of itself, SAS Survival Guide, and FM21-76. The benefit to this book is the cover is rubberized and the paper is thick glossy archival type print, meaning ti will be partially water resistant. I still don't want it wet if i can help it tho! The diagrams are nicely printed color and pretty darn clear. I think SAS Survival Guide edges it out in content, as well as FM21-76, but on the whole, having the different books to choose from is quite nice.
