STATUTORY STRENGTH.
The act of Congress of August 29, 1916, increased the authorized strength of the Marine Corps from 344 officers and 9,921 enlisted men to 597 officers and 14,981 enlisted men, and the President was authorized in an emergency to further increase the corps to 693 officers and 17,400 enlisted men, which he did by Executive order on March 26, 1917.
On April 6, 1917, Congress declared “that a state of war exists between the United States and the Imperial German Government” and one and one-half months later, on May 22, 1917, temporarily increased the authorized strength to 1,197 commissioned officers, 126 warrant officers, and 30,000 enlisted men. Finally, the act of July 1, 1918, temporarily increased the Marine Corps to 3,017 commissioned officers, 324 warrant officers, and 75,500 enlisted men, which is the maximum strength ever authorized for the Marine Corps. Of this number 17,400 were permanent and 57,650 temporary. In addition to the above, the act of August 29, 1916, which established the Marine Corps Reserve, permits the enrollment of reserves without limit as to number, and on April 6, 1917, there were enrolled, subject to call to active duty, three Reserve commissioned officers, 24 National Naval Volunteer officers, 36 Reserve enlisted men, and 928 enlisted National Naval Volunteers.
