A few days ago, at a white elephant gift exchange, a retired Staff Seargent with a Combat Engineers battalion in the US Marine Corps who saw combat in Iraq, opened a gift containing what he called, "a box of 22 shells." They weren't empties either. This guy and his battalion have probably delivered more ordnance in a live fight than all the pendants on the internet combined. I don't think he cares what the proper name of the stuff is called, as long as his team delivers it, and the enemy gets it.
