Originally published in 1946 and long out of print, I found it an outstanding read. But although I gave it four stars, I doubt if everyone would enjoy it - it is written specifically for a military audience and those with no experience and little knowledge of tactical military intelligence probably wouldn't have as much fun poring over it as I did.
The book is geared for battalion and regiment (brigade) S-2s, and distills lessons learned from WWII combat ops. It is written in very straightforward language, and covers a broad spectrum of responsibilities, from collection management, analysis, and dissemination to the use and management of CI, HUMINT, linguist and other assets. The authors speak strongly and repeatedly to issues that we continue to address today, such as clear and concise intelligence writing, effective collaboration among echelons and the importance of understanding threat and local (not always the same) culture and language even in conventional maneuver combat. A must read for anyone in Military Intelligence.
