Brought back from the dead.... wanted to add some titles...
For information on SEAL's, there is a 3 book series from Dick Couch:
The Warrior Elite
The Finishing School
and Down Range
The Warrior Elite follows a class as it goes through BUD/S, The Finishing School follows SQT, or SEAL Qualification Training, a much less well know component of earning the SEAL Trident, and Down Range (Which I have yet to read) I assume follows there deployment in theatre.
Another good series of books is about LRP's(Long Range Patrols) and LRRP's (Long Range Recon Patrols) in Vietnam, a 3 books series from 3 different authors, books 1, 2, and 3 in the Six Silent Men series. These guys were badass, and were in the lineage of the 75th Infantry, Rangers, when there wasn't an offical unit.
Another book on Vietnam Special Operations would be SOG by John Plaster.
Another good book is called Commandos by Douglas Waller. Goes into details about SEALs, SF Qualification Course, and AF Special Operations Pilots flying the Pave Low.
Yet another good book is Masters of Chaos, a recent history of US Army Special Forces. I am still reading this, and find it a pretty good book.
