Dirt.

It's true what they say, and in eight years it had been a pretty rough hall; those boots could probably take a few more miles and the rifling on his gun was sure, sure enough for about, let's say, four more shots at close range.  But the thing about it,  the thing is, is that although Douglas Ancoopers training had worn thin. 

One pair of socks for eight years.  Cost-cutting austerity.  And sure, this wasn't the real military.  The military with exo-suits and top-o-the-line satellite lasers so accurate they could bore-out the medulla-oblongata of a field mouse, if field mice have those.  This was the Salvation Army, and god-dammit, they had a mission.
