Gray Man

There’s an idea called “gray man”, in the security business, that I find interesting. They teach people to dress unobtrusively. Chinos instead of combat pants, and if you really need the extra pockets, a better design conceals them. They assume, actually, that the bad guys will shoot all the guys wearing combat pants first, just to be sure. I don’t have that as a concern, but there’s something appealingly “low-drag” about gray man theory: reduced friction with one’s environment.
