Aluminum? WTF, that is a pile of empty .38 Special brass, no aluminum in them, just copper and zinc. A round which, by the way, the military hasn't issued as a standard item for nearly 20 years, and even back then it was pretty much only air crew and criminal investigators that carried them. What the Hell does that pic have to do with her stupid post? A pile of beer cans or an aircraft would have been more relevant, and the half-wits over there probably would have even thought the latter to be a clever anti-military snark.
FAIL.
