Historians seldom concern themselves with the future, but understanding the past can provide valuable insights into what lies ahead of mankind—especially when it comes to war. Military luminaries and ordinary soldiers alike have devised countless war tactics throughout the ages by adapting better strategies, using new technologies, or taking advantage of geographical aids. Troops have to deal not only with literal battlefields but also with cultural ones. Although military technology has never stood still, it progresses more slowly than one would assume; its development consists of an evolutionary process more than anything else. Economic warfare is more common than it was in the past, since it imposes both diplomatic pressure and financial harm on opponents. One cannot prepare for every possible event or scenario, but the better the US is prepared for the aforementioned cases, the higher the nation's chance of remaining undefeated in future wars.
