One of the most incredible things is that so many of our 'modern' inventions and, thus, way of life, have their direct origins in the war. As well as being a terrible period showcasing the worst of the human race, it pushed and developed inventions at a rate that has never been equalled.If necessity is truly the mother of invention, it makes sense that the military would be on the forefront of innovation. When an advance in technology can mean the difference between life and death, research becomes incredibly important. Many technologies made for the battlefield have entered the civilian world and improved countless lives.
