Most military services teach "attention to detail." That the slightest lack of attention to detail can result in lives lost.

The fellows pictured here are not military, and certainly not in combat. They are local SWAT teams in upstate New York, the small town of Mohawk, population 7,500, and they're surrounding an alleged killer holed up in a local business.

What's telling about this picture though is that the officer with the "military style" assault weapon and the $500 "military style" close quarters combat sight has that same combat sight attached to the rifle backward.

CORRECTION: An earlier version of this story listed this officer as part of FBI HRT. The officer was in fact part of the area SWAT team.
