Legion of Merit Medal, Chief Commander

The Legion of Merit (LOM) is a military award of the United States Armed Forces that is given for exceptionally meritorious conduct in the performance of outstanding services and achievements. The decoration is issued to members of the seven uniformed services of the United States as well as to military and political figures of foreign governments.
The Legion of Merit (Commander degree) is one of only two United States military decorations to be issued as a neck order (the other being the Medal of Honor) and the only United States military decoration which may be issued in award degrees (much like an order of chivalry or certain Orders of Merit).

Chief Commander is awarded to Head of state or government. However, this degree was awarded by President Roosevelt to some Allied World War II theater commanders, usually for joint amphibious landings or invasions. (The President had this power under Executive Order 9260 of October 29, 1942, paragraph 3b.
