U.S. Military Enlisted and Officer Rank Insignia

Background

In the U.S. Military services, rank determines who gets to tell whom what to do. The higher one's rank, the more authority (and responsibility) they have. U.S. Military personnel fall into one of three categories: (1) enlisted members, (2) warrant officers, and (3) commissioned officers. Warrant officers outrank all enlisted members, and commissioned officers outrank all warrant officers and enlisted members.

"Rank" and "pay grade" are closely associated terms, but not quite the same. "Pay grade" is an administrative classification, associated with a member's pay. "Rank" is a title and denotes the member's level of authority and responsibility. An E-1 is the lowest enlisted pay grade. That person's "rank" is a "Private" in the Army and Marine Corps, an "Airman Basic" in the Air Force, and a "Seaman Recruit" in the Navy and Coast Guard. In the Navy and Coast Guard, the term "rank" is not used among enlisted Sailors. The proper term is "rate."

Service members in paygrades E-1 through E-3 are usually either in some kind of training status or on their initial assignment. The training includes the basic training phase where recruits are immersed in military culture and values and are taught the core skills required by their service component.

Basic training is followed by a specialized or advanced training phase that provides recruits with a specific area of expertise or concentration. In the Army and Marine Corps, this area is called a military occupational specialty; in the Navy it is known as a rate; and in the Air Force it is simply called an Air Force specialty.

Leadership responsibility significantly increases in the midlevel enlisted ranks. This responsibility is given formal recognition by use of the terms noncommissioned officer and petty officer. An Army sergeant, an Air Force staff sergeant and a Marine corporal are considered NCO ranks. The Navy NCO equivalent, petty officer, is achieved at the rank of petty officer third class.

At the E-8 level, the Army, Marine Corps and Air Force have two positions at the same paygrade. Whether one is, for example, a senior master sergeant or a first sergeant in the Air Force depends on the person's job.

The same is true for the positions at the E-9 level. Marine Corps master gunnery sergeants and sergeants major receive the same pay but have different responsibilities. All told, E-8s and E-9s have 15 to 30 years on the job, and are commanders' senior advisers for enlisted matters.

A third E-9 element is the senior enlisted person of each service. The sergeant major of the Army, the sergeant major of the Marine Corps, the master chief petty officer of the Navy and the chief master sergeant of the Air Force are the spokespersons of the enlisted force at the highest levels of their services.

Additional Rank info

Ensigns started with the Army but ended with the Navy. The rank of Army ensign was long gone by the time the rank of Navy ensign was established in 1862. Ensigns received gold bars in 1922, some five years after equivalent Army second lieutenants received theirs.

"Lieutenant" comes from the French "lieu" meaning "place" and "tenant" meaning "holding." Literally, lieutenants are placeholders. The British originally corrupted the French pronunciation, pronouncing the word, "lieuftenant," while Americans (probably because of French settler influence) maintained the original pronunciation.

While majors outrank lieutenants, lieutenant generals outrank major generals. This comes from British tradition: Generals were appointed for campaigns and often called "captain generals." Their assistants were, naturally, "lieutenant generals." At the same time, the chief administrative officer was the "sergeant major general." Somewhere along the way, "sergeant" was dropped.

Gold is worth more than silver, but silver outranks gold. This is because the Army decreed in 1832 that infantry colonels would wear gold eagles on an epaulet of silver, and all other colonels would wear silver eagles on gold. When majors and lieutenant colonels received the leaves, this tradition would not continue. So silver leaves represented lieutenant colonels and gold, majors. The case of lieutenants is different: First lieutenants had been wearing silver bars for 80 years before second lieutenants had any bars at all.

Colonel is pronounced "kernal" because the British adopted the French spelling "colonel," but Spanish pronunciation "coronel", and then corrupted the pronunciation.

While rank insignia is important, sometimes it isn't smart to wear them. When the rifled musket made its appearance in the Civil War, sharpshooters looked for officers. Officers soon learned to take off their rank insignia as they approached the battle line.

The Air Force actually took a vote on their enlisted stripes. In 1948, then-Air Force Vice Chief of Staff Gen. Hoyt Vandenberg polled NCOs at Bolling Air Force Base in Washington, and 55 percent of them chose the basic design still used today. When the Air Force became a separate service in 1947, it kept the Army officer insignia and names, but adopted different enlisted ranks and insignia.

Officer Insignia

The commissioned ranks are the highest in the military. These officers hold presidential commissions and are confirmed at their ranks by the Senate. Army, Air Force and Marine Corps officers are called company grade officers in the paygrades of O-1 to O-3, field grade officers in paygrades O-4 to O-6 and general officers in paygrades O-7 and higher. The equivalent officer groupings in the Navy are called junior grade, mid-grade and flag.

Naval officers wear distinctively different rank devices depending upon the uniform they're wearing. The three basic uniforms and rank devices used are: khakis, collar insignia pins; whites, stripes on shoulder boards; and blues, stripes sewn on the lower coat sleeves.

Warrant Officers

Warrant officers hold warrants from their service secretary and are specialists and experts in certain military technologies or capabilities. The lowest-ranking warrant officers serve under a warrant, but they receive commissions from the president upon promotion to chief warrant officer 2. These commissioned warrant officers are direct representatives of the president of the United States. They derive their authority from the same source as commissioned officers but remain specialists, in contrast to commissioned officers, who are generalists. There are no warrant officers in the Air Force.
