What elements lead to victory in a battle?

I think... it is the backbone, the NCO, particularly the junior NCO in the Army. They understand their mission, the commander's intent and their task and purpose, and they get after it. I think the fact that our military powers down authority and responsibility is the difference maker for the U.S. Army and U.S. Marines. SGT Christopher Churilla

Every battle study was outlined by the Principle of War: MOOSEMUSS. Usually if you could score 5 out of 9 in those principles, victory would be secured. The 10th Principle: Dumb Luck.

I think to often victory is relegated to tactical or operational superiority. However what really wins a war is the strategic means of creating the desired change that concludes with a peace accord. As of late we have been able to win operationally and tactically due to our resources, manpower, technology and wealth however strategically our victories have been hollow. So I would say the resolve to maintain a strategy until a desired change is perceived by all belligerents and observers and is sustained with little or no effort.
