Named for Revolutionary War general and South Carolina native Thomas Sumter, Fort Sumter was one of nearly 50 forts built as part of the so-called Third System, a coastal defense program implemented by Congress in 1817.
In simple terms, the U.S. Armed Forces are made up of the five armed service branches: Air Force, Army, Coast Guard, Marine Corps, and Navy.
The Military Intelligence Corps is one of the basic branches of the United States Army. In 1971, the United States Army Intelligence Center was established at Fort Huachuca, Arizona as the home of the military intelligence branch.
