Jan Fischer, American Soldier In His Military Life

Military technology
As with any occupation, since the ancient times the military has been distinguished from other members of the society by their tools, the military weapons and military equipment used in combat. When Stone Age humans first took a sliver of flint to tip the spear, it was the first example of applying technology to improve the weapon.
Since then, the advances made by human societies and that of weapons has been irretrievably linked. Stone weapons gave way to Bronze Age weapons, and later the Iron Age weapons. With each technological change was realised some tangible increase in military capability, such as through greater effectiveness of a sharper edge in defeating leather armour, or improved density of materials used in manufacture of weapons.
