自石器时代以来,战争和武器就到处存在。那时的人们第一次为了土地和食物而用原始的石器相互争斗。罗马时代,最复杂的武器——例如弩和弹弓——依靠弹力来对敌人投掷发射物。后来,中国人发明了火药。它并没有对战争立刻产生影响,而是在大约400年后,火药才在战争中用于发射枪弹。但是其后果却永远地改变了战争的规模。 Since the Stone Age, war and weapons have been everywhere. For the first time, people struggled with primitive stone for land and food. Roman times, the most complex weapons - such as crossbows and slingshots - rely on the elastic to throw the enemy on the launch. Later, the Chinese invented gunpowder. It did not immediately affect the war, but it was only about 400 years after the gunpowder was used to launch a bullet in the war. But the consequences have forever changed the scale of the war.
