I'm beyond fighting in my country's wars. Been there, done that. A comment by Andrew, though, brought an image to mind that I will share with you. It persisted for lifetimes but perhaps no more than 50 years when the perfectly trained young officer would indeed carry both a pistol and a sword. Officers still carry a sword but purely for ceremonial reasons. They are not allowed to use them on Capital Hill or in IRS offices. And, every house needs a cannon.
