It is also important to make sure your military equipment can travel across rough ground after the retreating enemy has destroyed all roads, rails, and bridges. Of course in that situation you don't care much about saving the ground you are covering while chasing the enemy, but lack of roads is not fatal (there is good reason the military likes it - it makes their logistic much easier on safe ground)
