At Ft. Campbell Ky. in late July, it's the only way to wear one.
The story is that I was part of the reaction team. We had just been hit with a chem threat and were standing down and taking things off when the chem detectors went off again and OPFOR hit us.
I went charging to the sound of the guns barely able to see through fogged lenses. OPFOR had already retreated (I was on the opposite perimeter at the time they hit). Unable to see, I wandered past our perimeter and found myself on a slight ridge above the OPFORs rally-point.
A 100-round box of 7.62 later the referees declared their entire unit (15-20 guys) wiped out and their mission a failure. My unit S-3 snapped the pic as I wandered blind through the woods before I found the bad guys.
Of course, back then, I told everyone that I had stalked them.
An M-60 and a little luck can do great things. ;-]
