I, too, read the book, but I don't have any extra inside information. From the book alone, it seems like there was a real lack of cohesion and no unity of command, and that created all manner of problems. It wasn't just the Air Force that had trouble getting integrated...they cut the local guy, Zia Lodin, out entirely, and they landed three helicopters on the exact same hornet's nest of bad guys. The C2 was almost non-existent from the start of the mission.
