I just Googled it: https://en.wikipedia.org/wiki/United_States_Coast_Guard

The United States Armed Forces[6] are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, and Coast Guard.[7] The President of the United States is the military's overall head, and helps form military policy with the U.S. Department of Defense (DoD), a federal executive department, acting as the principal organ by which military policy is carried out.

Wiki says "The United States Coast Guard (USCG) is a branch of the United States Armed Forces[14] and one of the country's seven uniformed services."

I'll have to read that to see what the SEVEN are!
