Whenever it stinks, look into it. I know y'all won't because it aligns with what you want to hear but the applicable Army Regulation goes back to 1992:<quoted text>Under a 1993 order passed by then-President Bill Clinton, carrying a private firearm on a military base was banned on military bases in the United States. Individuals could privately own firearms if they lived on base, but those firearms could not be carried on the person while on base. This order was revised on Pentagon orders in 2010, and now specifically requires that every private gun brought onto base be registered with the Military Police. The rules also require harsher enforcement of rules forbidding the carrying of private firearms on base.
* If George Washington had learned that soldiers under his command had died from a turncoat attack within an American Fort — not because arms weren’t available for his men to defend themselves but because an American officer didn’t trust American soldiers to bear arms — I’m fairly certain that American officer would have been summarily executed by the same firing squad as the turncoat.
