Getting lost sucks. There's simply no better way to describe it. Getting lost in a place where you are likely to die unless you get un-lost in a hurry sucks even more. One thing you can carry with you on your adventures, whether in the military or as a civilian, is a good lightweight strobe light. The one I originally carried was the SDU-5/E strobe (with both the IR and "blue light" filters) which was issued to aircrews as a piece of survival kit. But as batteries became harder and harder to find (the SDU-5/E takes a mil-spec BA-1574/U mercury battery, which, if you can find it, will run you $30-40 each) I switched over to the ARC MS-2000(M) strobe. While slightly larger than the SDU-5/E, it comes complete; the IR and blue light filters are incorporated into the construction, and, most importantly, it runs off of AA batteries.
