To be a marine, you gotta have faith.

It has four divisions and works out of about 35 bases and stations in the US and Japan. It is the smallest of the military branches with just more than 202,000 active duty personnel and some 40,000 reservists. The Marine Corps traces its roots to the American Revolution and 1775, when the Continental Marines was formed.
