LOL - "Often considered the first machine gun, the Puckle Gun or Defence gun was a tripod-mounted, single barrel flintlock gun with a multi shot revolving cylinder. It was designed for use on ships to prevent boarding and could fire 63 shots in seven minutes. But what makes this weapon weird and unique is that it was capable of firing two types of bullets, round bullets to be used against Christian enemies and square bullets to be used against Muslim Turks. The square bullets were thought to be more painful and according to the patent would convince the Turks of the benefits of Christian civilization"
Maybe we need to send some square bullets out to afghanistan to convince them?
