I recently had the pleasure of talking about military capability to the Australian Command and Staff College. One of the topics I wanted to cover was the impact of technology on warfare. The first thing that came to mind was Winston Churchill\u2019s musings on the Bronze Age from his History of the English-Speaking Peoples<\/em>:<\/p>\n

While what is now our island was still joined to the continent another great improvement was made in human methods of destruction. Copper and tin were discovered and worried out of the earth; the one too soft the other too brittle for the main purpose, but, blended by human genius, they opened the age of bronze. Other things being equal, the men with bronze could beat the mean with flints. The discovery was hailed, and the Bronze Age began.<\/p><\/blockquote>\n

Putting Churchill\u2019s dodgy timelines to one side in favour of literary merit (Britain was disconnected from the continent by the English Channel long before the Bronze Age), this prose neatly captures the sometimes revolutionary impact on warfare of developments in technology. Reinforcing the point, two pages later Churchill summarises another technological revolution in military affairs\u2014and another sweep of history\u2014with a chillingly efficient sentence: \u2018Men armed with iron entered Britain from the Continent and killed the men of bronze\u2019.<\/p>\n

A little more digging around led me to this essay<\/a> on the impact of science and technology on war fighting. For the purposes of this week\u2019s graph, I\u2019ve redrawn one of the figures in the article to make the trends under discussion clearer. Figure 1 (click to enlarge) shows the steadily increasing effectiveness of weapon systems since 1000 AD. The measure of effectiveness here is the amount of energy delivered per solid angle per unit time\u2014in effect a hybrid measure of the terminal effect of the system, the time taken to deliver that effect and its accuracy.<\/p>\n

We can argue a little about the way the numbers are calculated but the basic point is sound\u2014there has been a breathtaking rate of increase in lethality and the swiftness and accuracy with which it can be delivered. There was about two thousand years between Europeans mastering bronze and iron, and the difference in battlefield effectiveness between those technologies was many times less than some of the later changes, which occurred on much smaller time scales. That\u2019s mostly because the terminal effect was the only factor that changed\u2014it still took months to assemble an army and march it into position, and weapon accuracy still depended on the skill of its user. But in the twentieth century alone, weapons have increased in effectiveness by a factor of one hundred million by this compound measure.<\/p>\n

\"Weapon<\/a><\/figure>\n

Another graph (click to enlarge) shows one result of these developments\u2014a dramatic decrease in the number of combatants who can assemble on the battlefield with any degree of safety. Simply put, when faced with modern weapons, the battlefield is too dangerous for any significant assembly of personnel.<\/p>\n

\"Density<\/a><\/figure>\n
