Good Review of the Intel Disciplines

Format: Kindle

I rented this book as required for an intelligence collections course I as taking. It is a good rundown on the different INT disciplines and the bureaucratic organizations managing the different INT categories. This book does not really touch on the various collection programs used to manage collections, or what the nomenclature of those requirements are, so reading this book will not teach you about intelligence collection management beyond gaining a foundational understanding of what the various INTs are used for.

Don't buy school books from Amazon

Format: Paperback

Thought I bought new, book came with an obsurd "Amazon Rentals" sticker on it. Looks used and abused. Will not be buying books needed for school from Amazon ever again.
