POAC, the "Tank"-if you want to know more about these Pentagon institutions, this book is for you. Readably written by a retired Air Force general with a wealth of experience in the Pentagon hallways and folkways, the book is primarily nuts and bolts-complete with maps and a nine-page glossary of Pentagonese-but it also gives a flavor of how the Goldwater-Nichols reorganization affects the work of the Joint Chiefs of Staff.
