remained a considerable percentage in all European armies. Size of field armies This has been dictated through history by logistical constraints, mainly the supply of food. Before the mid-17th century, armies basically lived off the land. They didn't have supply lines; they moved to the supply, and many times their movements were dictated by supply considerations. While some regions with good communications could supply large armies for longer periods, still they had to disperse when they moved from these well supplied areas. The maximum size of field armies remained under 50,000 for most of this period, and strength reports over this figure are always from unreliable narrative sources and must be regarded with scepticism. In the second half of the 17th things changed greatly. Armies began to be supplied through a net of depots linked by supply lines, that greatly increased the size of Field Armies. In the 18th century and early 19th century, before the advent of the railway, the size of Field Armies reached figures over 100,000. Conclusion The theory of a military revolution based upon technology has given way to models based more on a slow evolution in which technology plays a minor role to organization, command and control, logistics and in general non-material improvements. The revolutionary nature of these changes was only visible after a long evolution that handed Europe a predominant place in warfare, a place that the industrial revolution would confirm. Some historians have begun to challenge the existence of a military revolution in the early modern period and have proposed alternative explanations. The most radical revisionist views of the theory consider it unable to explain the military developments of the Early Modern Period and the hegemonic rise of the West. The new wave of revisionist historians reject completely the idea of a military revolution and base their position on close analysis of the gradual and uneven transformation of tactical, operational, and technological aspects of European warfare over the course of the late Middle Ages and Early Modern period, as well as in their assessment of similar military experiences among non-Western countries, namely, Japan, Korea, the Mughal Empire, and the Ottoman Empire.
