Tod D. Wolters, the former pilot, who has served in Afghanistan and Iraq, has been declared as the Supreme Allied Commander Europe during the ceremony at NATO's (The North Atlantic Treaty Organization) military headquarters in Mons, southern Belgium. This is one of the most challenging and extremely important military positions in the world. US Air Force General Tod D. Wolters who is supposed to run for a tenure of 2 to 3 years, was preceded by U.S. Army General, Curtis M. Scaparrotti. Wolters will also be the commander of U.S. forces in Europe across more than 19 million square miles. This area includes 104 countries in Europe, Africa, Asia and the Middle East, the Arctic, Atlantic, and Indian Oceans, contains more than a quarter of the world's population, and generates more than a quarter of the world's gross domestic product (GDP). An American military officer always holds the NATO post of SACEUR (The Supreme Allied Commander Europe).
