Military was any organization that is dedicated to the defense of a certain nation. Most militaries were organized by an agency of a nation's government. For example, the United States Military was organized by the United States Department of Defense. Militaries were tasked with protection of their countries and every military officer, which was usually called a soldier, was trained in the art of combat, weapon use, particularly firearms, protocol and the operation of military vehicles.
There were many different types of militaries that were often deployed by such agencies in times of war, or other crises. There were military organizations that operate on land, sea, air and in outer space.
