Understanding Special OperationsThe book is now available from Dave Ratcliffe.
But what's even better, is the entire book is available on-line. Go to his site read some of the ground breaking research Dave has done, This book is a must have for anyone who already has the Prouty CD-ROM.
I personally recommend it as the best book anywhere for this topic.
