History provides durable blueprints: "what to do," and sometimes, more importantly, "what not to do." In the end, each lesson can be summed in one word: preparation. As long as warfare exists, its principles, leadership, strategy, and beliefs makes it relevant for every modern Soldier. These principles are imbedded through historical study. Modern Soldiers in turn will become a part of history, and the cycle will continue. All military professionals should consider one item essential alongside his or her uniforms, medals, and artillery: a history book. History can indeed prove move effective or more dangerous than any gun; after all, those who do not heed history are destined, or doomed to repeat it.
