Ed West on the beginning of the end of military aristocracy in Europe and the rise of the merchant class:
The medieval system began with the Franks, whose mastery of cavalry made them the most powerful tribe in the former western empire. Later, the Normans used horses in far larger numbers and developed the cavalry charge, used to lethal effect at the Battle of Hastings. Cavalry underpinned the European social order because only those with a reasonable amount of land could afford the destrier warhorse, which cost 30 times as much as a regular farm animal and could carry up to 300lbs in weight, including 50lbs of iron armor — itself very costly.
The sons of the aristocracy were mostly schooled in warfare from a young age and despised learning and trade, which were viewed as dishonorable, leading to an excess of landless younger sons whose only skill was fighting, many of whom found their way to wars, or caused them, or made a living at absurdly dangerous tournaments. Cavalry developed certain rules — chivalry, which primarily concerned the treatment of aristocratic prisoners — as well as an idealization of the aristocratic warrior through the stories of Arthur, Lancelot, and Roland that singers recited at the courts of dukes and counts.
This order was first shaken in 1302 when France’s cavalry confidently marched north to suppress a revolt by the Flemish. Flanders is not naturally rich in resources — Vlaanderen means flooded — but its people had turned swamps into sheep pastures and towns, building a cloth industry that made it the wealthiest part of Europe, its GDP per capita 20 percent greater than France and 25 percent better than England. The wealth of Flanders’ merchants was such that when Queen Joan of France visited, she afterward wrote in horror that: “I thought I would be the only queen there, but I find myself surrounded by 600 other queens.”
The Flemish were traders, not knights, which is why the French were sure of victory. And yet, with enough money to pay for a large, well-drilled infantry, they were able, for the first time, to destroy the cavalry at the Battle of the Golden Spurs. It was the beginning of the end. No longer could the aristocracy simply push around the bourgeoisie, and as the latter grew in strength, it undermined the violence-obsessed culture of the nobility.

The aristocratic class that wished for glory in battle was in retreat, and yet, despite this, won the narrative. While in exile in Burgundy, King Edward had met a London merchant by the name of William Caxton who in his spare time transcribed books for aristocratic women. Exhausted at the toll of work, he learned through business contacts of a new technology in Germany, called movable type; when Caxton brought a printing press back home one of the most successful books he published was Thomas Malory’s The Death of Arthur.
It became the influential work in celebrating the Heroic Narrative of the Middle Ages, but the aristocratic ideals it harked back to were mostly a sham and ultimately rested on the rusty sword (and Malory was a convicted rapist). No account of any trader or banker could ever compete with these knights’ tales, of course, and yet you could argue that they were the real heroes who shaped our world.
Thanks to a post at Army.ca, here is the rough outline of the NATO 
There is an old, tried and true, military expression to describe this: “it’s a dog’s bloody breakfast!” Can you imagine trying to command and control that organization? Especially under NATO’s rules that, as we saw in Afghanistan, allow each country to impose caveats on what where when and how its forces may be
