From the New York Times Magazine: How to Save a Soldier, a description of the training of Army medics. Field medicine and wilderness medicine are fairly closely related, and innovations from the military sometimes filter down to both emergency room and backcountry care. The military has also been critical in performing research on both physiology the effectiveness of field treatments. Navy swimmers, for example, have participated in extensive aquatic hypothermia experiments (the punch line: get _out_ of cold water; even with a cold wind blowing, you're far better off in the air than in the water, which conducts heat away from your numb body far faster than the wind). The NYT article above notes a recent article in The Lancet that reconsiders field medicine in light of lessons learned in Mogadishu, Somalia.
