US Army Ranger Handbook

Has good sections on survival and first aid. As you might expect from an Army manual, not written with much flair!, but rather a dry (but useful) information guide. 

This handbook offers the techniques and tactics that make Army Rangers the best soldiers in the world. These highly-trained, easily-deployable, and widely-skilled infantrymen specialize in airborne assault, raids, recovery of personnel and equipment, and airfield seizure, among other difficult and dangerous missions. Drawing from over two centuries of bloody lessons learned in special operations combat, this guide gives modern soldiers the best advice possible. In straightforward language and a no-frills style, it covers deception, stealth, communications, escape and evasion, ambush operations, perimeter defense, counterintelligence, and much more. Handy and concise, this manual was designed so Rangers could easily carry it into the field. Now it is the ultimate resource for anyone who wants to know how Rangers think and work.
