The United States Army is a branch (or section) of the United States Armed Forces. An Army mainly deals with land based missions, while other parts of the military deal with air and sea missions. The current Commander-in-Chief of the United States Army is President Joe Biden.
The United States Secretary of the Army, a civilian, leads the army with the help of the Army Chief of Staff, a general. Members of an army are called soldiers. When people join the army, they must serve for a certain amount of time called a "tour of duty". A new soldier or recruit goes through Basic Training at a training camp to become a soldier. Each soldier is trained in weapons and equipment that they will operate to carry out missions.
