War has brought the world some pretty impressive, if horrific, things. Nuclear weapons, enormous warships, an ever-diversifying parade of guns, all of them dreamed up in the depths of some military design bureau in response to the demands of war.
The multitude of arms races, from strategic weapons to bullets and uniforms, results in an unending stream of innovations for the use of the world's various military.
It's no surprise that, say, a type of missile or body armour was invented as a direct result of war. What is more surprising is how many everyday household items, inventions that have apparently nothing to do with warfare, were created because of it. Some had a military application that could be crossed over into civilian life, while others were accidental discoveries made while trying to develop something else.
Depending on your point of view, the contribution of warfare to technological innovation is either impressive or deeply disheartening. Either way, the demands of the military have driven the invention of things around you, and it doesn't look like that's going to change any time soon.
