The CIA is at top of a cosmology of government and private concerns known collectively as the intelligence community. One of the most important components of this community is the U.S. Army Intelligence Center. Its mission is to provide information to commanders at all levels in the U.S. Army so that they are able to determine the capabilities of a foreign foe or act quickly on accurate, up-to-date intelligence. Now for the first time ever, the recently declassified U.S. Army Counter Intelligence Handbook provides a rare look into the specialized and secretive world of military intelligence and counterintelligence procedure. Counterintelligence comprises efforts to determine what the enemy knows, efforts to keep friendly intelligence secret, and efforts to hamper the enemy's ability to collect and use intelligence. In this manual, the first four chapters provide counterintelligence information to the commander and his staff, while the remaining chapters go over the nuts-and-bolts of counterintelligence operations. The U.S. Army Counterintelligence Handbook is a must-read for anyone with an interest in today's difficult military intelligence questions.
