Query: Unmasking Of The NVA-VC

A very revealing work. Gives the anatomy of North Vietnamese Army and Viet Cong units, as well as their operational applications. Discloses the broader regional political objectives of the North Vietnamese communists as it relates to subjugating Laos and Cambodia, and in doing so verifies the "domino theory" that so many critics of the war were quick to label as "fabricated." "Secrets" is a good military "X's and O's" of how a "just cause" was allowed to suffer from geopolitical naivete, and the ultimate price that was paid.
