Delta Force: A Memoir by the Founder Charlie A Beckwith - I like a good bit of military history and it always amazes me that some of the best, most ingenious ideas seem to hit the same bureaucratic crap in every military in the world. Rogue Warrior by Richard Marcinko is about him creating Seal Team Six and that is filled with exactly the same "we have an urgent need for a specialist unit but the bureaucracy nearly kills it" story as the Delta story is.
Infact, I've read dozens of books on Israeli, South African, Rhodesian and other "western" forces and it seems that in every military there are people who just should never be allowed to wear a uniform based on their god awful decisions. I mean they might be ideal bank managers or accountants but they should never in charge of a fluid ever-changing military situation which needs "not in the manual" thinking to solve.
