It is often important to remember that however technology may have evolved, the people who use this technology have not. An example of this fact can be seen in the use of swords in modern warfare. I recently came across an article by Bou Jean which examines the introduction of sword usage into the Australian Mounted Division’s training programme in 1917-1918.
Although never considered as a replacement for modern firearms, the sword became an important element of shock tactics when charging Turkish machine gun positions: “the rapid rush of the horsemen and the sight of the steel had its usual unnerving effect.” (123) The intimidation of encountering mounted sword-wielding enemies has clearly not diminished.
