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 eight uniformed services of the United States as well as to military and political figures of foreign governments.
The United States Armed Forces are the military forces of the United States. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. The president of the United States is the commander-in-chief of the armed forces and forms military policy with the Department of Defense (DoD) and Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All six armed services are among the eight uniformed services of the United States.
Rear admiral is a senior naval flag officer rank, equivalent to a major general and air vice marshal and above that of a commodore and captain, but below that of a vice admiral. It is regarded as a two star "admiral" rank. It is often regarded as a two-star rank with a NATO code of OF-7.
Lieutenant commander is a commissioned officer rank in many navies. The rank is superior to a lieutenant and subordinate to a commander. The corresponding rank in most armies and air forces is major, and in the Royal Air Force and other Commonwealth air forces is squadron leader.
Second lieutenant is a junior commissioned officer military rank in many armed forces, comparable to NATO OF-1 rank.
Commander is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain.
Ensign is a junior rank of a commissioned officer in the armed forces of some countries, normally in the infantry or navy. As the junior officer in an infantry regiment was traditionally the carrier of the ensign flag, the rank acquired the name. This rank has generally been replaced in army ranks by second lieutenant. Ensigns were generally the lowest-ranking commissioned officer, except where the rank of subaltern existed. In contrast, the Arab rank of ensign, لواء, liwa', derives from the command of units with an ensign, not the carrier of such a unit's ensign, and is today the equivalent of a major general.
General of the Armies of the United States, more commonly referred to as General of the Armies, is the highest military rank in the United States Army. The rank has been conferred three times: to John J. Pershing in 1919, as a personal accolade for his command of the American Expeditionary Forces during World War I; to George Washington in 1976, as a posthumous honor during the United States Bicentennial celebrations; and posthumously for Ulysses S. Grant in 2022 to commemorate the 200th birthday of the Army's first four-star general.
Commodore was an early title and later a rank in the United States Navy, United States Coast Guard and the Confederate States Navy, and also has been a rank in the United States Public Health Service Commissioned Corps and the National Oceanic and Atmospheric Administration Commissioned Officer Corps and its ancestor organizations. For over two centuries, the designation has been given varying levels of authority and formality.
In the United States Armed Forces, the ranks of warrant officer are rated as officers above all non-commissioned officers, candidates, cadets, and midshipmen, but subordinate to the lowest officer grade of O‑1. This application differs from the Commonwealth of Nations and other militaries, where warrant officers are the most senior of the other ranks, equivalent to the U.S. Armed Forces grades of E‑8 and E‑9.
Captain is the name most often given in English-speaking navies to the rank corresponding to command of the largest ships. The rank is equal to the army rank of colonel and air force rank of group captain.
In the United States Armed Forces, a major general is a two-star general officer in the United States Army, Marine Corps, Air Force, and Space Force.
Lieutenant is a commissioned officer rank in many English-speaking nations' navies and coast guards. It is typically the most senior of junior officer ranks. In most navies, the rank's insignia may consist of two medium gold braid stripes, the uppermost stripe featuring an executive curl in many Commonwealth of Nations; or three stripes of equal or unequal width.
