A few more I would add ( not sure if they are "professional" enough but all very insightful and similar to the existing ones on that list ).
1. Boyd ( http://www.amazon.com/Boyd-Fighter-Pilot-Who-Changed-ebook/d... ) - Came up with the EM theory that gave the air force the analytical framework to analyze dog fighting maneuvers and aircraft. Known for authoring the OODA loop and leading the infamous Fighter Mafia that gave us the F-16 and F/A-18
11. The Yom Kippur War ( http://www.amazon.com/Yom-Kippur-War-Encounter-Transformed-e... ) - an account of the Yom Kippur War and how the Israelis were blind to the innovations of the Egyptian army that upended its defense strategy based on tanks and aircraft and also how a near victory for the Egyptians allowed them to negotiate a peace with Israel.
