What an extensive subject this is! Multiples of books have been written that have good material in them. The problem is that they only work for a short period of time or until the level of warfare gets beyond the level of the revelation given.
May of God's people hide behind the basic principles of warfare. They are good and work at certain levels of war. God allows them to work, but, there is a passage of scripture that has caught my attention recently. I do not necessarily like it, but, it is there for me to wrestle my way through.
"He teaches my hands to war and my fingers to fight, so that a bow of steel is broken in my hand." The question becomes, How does He teach me these things?
He does it by arranging experiences so that I am confronted by the enemy in a field or area that I have not been exposed to before. Remembering that we fight on three fronts, this is not necessarily an easy way to go. We fight the world, the flesh, and the devil. There are times when that war is on all three fronts at the same time. with the first two being drawn upon by the last one.
