[Scimitar]

As I have been researching SF in general and the 18D MOS specifically, I have come across a book that I found incredibly helpful in understanding what the SF medic really does.

Yes, there are small stories here and there, and the job descriptions that can be found on-line, but this book went into a high level of vivid detail; very well written.

Warrior Healers - The untold story of the Special Forces medic - Book 1: The Beginning.
Leonard D Blessing Jr.

Warrior Healers mainly focuses on the Foreign Internal Defense (FID) & Unconventional Warfare (UW) part of the SF mission.

To gain a similar understanding of the 18Ds role in the Direct Action (DA) part of the SF mission; I would recommend "Rough-Neck Nine-One" which has been extensively discussed on this site.

I found, as Frank Antenori's original MOS was as an 18D, the book to provide excellent examples of the mass crisis events that an 18D is required to handle.

Both can by found on Amazon.com
