How many Marines are in the US Marines?

Answer 1

About 200,000 US Marines. They have the French Foreign Legion outnumbered 25 to one.
Prior to the global war on terror the US Marines had an active duty strength of approximately 183,000. This includes Officers and Enlisted. This end strength is set by Congress (as it is for all services). The Marine Corps also has a sizable reserve made up by both active duty Marines that have served at least one full term of enlistment on active duty, as well as reservists that served only on active duty for training. Frequently the US Marine Corps would "get around" the limitation on end strength by bringing reservists on active duty for periods of up to one year to augment the active duty corps, and these reservist did not count against the active duty end strength.

Since the GWOT, congress approved a significant increase in the active duty end strength to something like 225,000. This does not include the Marine Reserve units that were activated for the 2nd Gulf War to bulk up the US Forces in Theater.

The US Marines are a smaller service because they are considered elite and hold themselves to a higher standard than virtually all military services around the globe. They are in fact the largest all elite force on earth.
