===Mobility===
Mobility, which determines how quickly a fighting force can move, was for most of human history limited by the speed of a soldier on foot, even when supplies were carried by beasts of burden. With this restriction, most armies could not travel more than {{convert|32|km|mi}} per day, unless travelling on rivers. Only small elements of a force such as [[cavalry]] or specially trained light troops could exceed this limit. This restriction on tactical mobility remained until the latter years of [[World War I]] when the advent of the tank improved mobility sufficiently to allow decisive tactical manoeuvre. Despite this advance, full tactical mobility was not achieved until [[World War II]] when armoured and motorised formations achieved remarkable successes. However, large elements of the armies of World War II remained reliant on horse-drawn transport, which limited tactical mobility within the overall force. Tactical mobility can be limited by the use of field obstacles, often created by [[military engineering|military engineers]].{{sfn|Holmes et al.|2001|p=895}}
