the changes in warfare between the medieval-renaissance era, and the early modern period of Gustavus Adophus, Frederick the Great, and Napoleon, are most evident in the adoption of increasingly sophisticated logistics. Gustavus Adolphus was the first modern general to equip his army with govenment supplied issues of boots, (no left or rights, the soldier was expected to switch them each day to increase their longevity). Frederick introduced the modern supply "branch", previously all supply wagons and cannon limbers were operated and often owned by civilian drovers who tended to dissapear when bullets and cannonballs started flying for some reason... which was not ideal for keeping powder and iron flowing into the guns.  So Fritz ordained that the drivers would hence forth be soldiers that could be flogged if the absconded with the supplies just when they were most needed. One of the many "age of reason" innovations was standardization, which required contactors to work to goverment patterns, overseen my military inspectors, and one of the more interesting military patterns to arise in the 1700s was the "wurst wagon" at once clever and fiendish. It is essentially a weather proofed ammunition wagon that allowed a whole gun crew to ride it for long marches. It's genius is that it saves wear and tear on artillery boots, reduces the livestock needed to transport a battery, can ford rivers keeping the powder dry, and supplies a weatherproof storage place for artillerists to hide crackers and brandy. On the other hand, it hardly seems dignified, and you can imagine what the tailbone and buttocks must have felt like after hours on an unimproved napoleonic road with no springs...
