United States Army
The United States Army is a branch (or section) of the United States Armed Forces.
An army mainly deals with land based missions and operations. The army started as the Continental Army from 1775 to August 7, 1789 when the War Department (now known as the Department of Defense) was formed. The United States Secretary of the Army, a civilian, leads the army with the help of the Army Chief of Staff, a general.

When a person joins the Army, they must serve for a certain amount of time or a "tour of duty". A new soldier or recruit must go through training called Basic Training to become a soldier. Each soldier is trained in a variety of weapons and equipment to carry out commands.
