Query: Great book on the Brandenburgers

These men were the 1st official SOF. They were unique men from all over the world who chose to serve Germany. They had multiple skill sets. This book discusses the details of the intelligence agency which they answered to. It discusses their organization which I found to be very detailed. It also covered many of their missions which took place all over the world. Outstanding book on a special breed of men whose efforts were in vain.
