Not that you would ever impersonate a police officer or pull people over and write fake tickets or anything. But it's not against the law to do a little fantasy role-playing, is it? At the Army Store, for $4 to $12 you can find a really cool, battle-grimy blood-red beret that makes you look like a soldier of fortune, or a cloth cap with a stingy little brim on the front and extra-long earflaps. Nothing like dressing up as a North Korean border guard to make the neighbors nervous. You also can be "U.S. Marine Corps—Retired," or a naval officer, but that costs $29.99, and you have to learn how to snap a proper salute. For $10.99 you can don a very chic burgundy boho topper. How very armies of the night.
