Military achievements refer to significant accomplishments by armed forces during conflicts or wars. These can include successful battles, strategic victories, or the development of advanced technologies that enhance combat effectiveness. Notable examples include the D-Day invasion during World War II, which marked a turning point in the war, and the invention of the tank, which revolutionized ground warfare. Such achievements often lead to changes in military tactics and can influence the outcome of wars. They may also result in the establishment of new nations or the redrawing of borders, as seen after the Treaty of Versailles following World War I.
