Many nations around the world observe some kind of Armed
Forces Day to honor their military forces. Armed Forces Day
is a joint celebration of all six branches of the U.S. military:
Air Force, Army, Coast Guard, Marine Corps, Navy, and the
newly created Space Force. The day honors all those who
are currently serving in the U.S. armed forces. This includes
the men and women who have served or are serving in the  
Army, Navy, Marine Corps, Air Force, Space Force and Coast
Guard, including the National Guard and Reserve components.
