as badass as it would be to have some chubby smaurai hacking his way through metal tanks, braided hair blowing in the wind as he deflected bullets and blood spattered across his mask....modern military simply isn't set up for it. even an argument could be made that swords have a place in the military we just don't roll that way.
a better question would be why did we ever move away from swords and towards guns. when we first started using them they were as likely to kill you as the other guy, and not even close to as accurate as a bow. the power i would guess was only marginally better if at all, but considering both could get the job done under any circumstance provided they connected the bows are vastly superior.
now a modern m16 i can understand being chosen over a sword. but a damn 1200's pistol over any other weapon? i just don't understand it.
The move to firearms was related to morale, the effect that a regiment of hand-cannoneers could have on the average-medieval-Joe was devastating. Most people had never even heard of gunpowder, a handful of shots was all it took to rout half the opposing army. Not to mention the effect it had on cavalry, even warhorses can be flighty if they don't know what to expect.
Well serious question or not - here's a serious and simple answer: Technology evolves over time and that includes what is used as weapons. Why use a weapon that requires you get get within just feet of a dangerous enemy for it to have any affect when you can blast them from a kilometer away with one of these
Go back to medievel times and I'm sure no-one asked "why are we using swords? why not just beat them to death with sticks"
What kind of katana are you talking about? I'm pretty sure it's impossible to do something like that unless its in some cartoon or movie. Also, a soldier armed with a modern assault rifle can gun down someone with a sword before they ever get close to cutting them.
Politics = is the way how a country is governed. Military = an organisation that defends its country with lethal force.
Big difference. Talking about this is nothing to do with politics.
Also, there is no psychical way in real life for a katana or other blades to slice through a tank with just human power alone. A katana would dull after a few hits of cutting through bone.A combat knife is more efficient in close combat, but guns are faster.
Anime tends to exaggerate everything. Katana can not slice through tanks. It's like using a glass hammer. Nice to look at, but useless.
Zombie apocolypse Panel at Fanime. They talked about the real life situation if you were to be a zombie and one of the weapons is katana. Its sharp, but you have to keep sharping as I recall. Good luck cutting more then one.
