The US Army components first began to develop at the end of World War I. The needs that were associated with the army at this time developed into several roles and duties that were needed for combat, specifically for preparation of war, combat, defense and extra assistance needed during peacetime. From this main ideal, were several divisions and components of the army that were developed to help those that were a part of the army.

At the beginning of World War I, there was only one organizational branch of the army, known as the National Army. After the end of this war; however, the military found that there was not the need to have the same roles among soldiers that were in the army. This led to three main components in the army, including the regular army, national guard and reserve. This division was created so there would be a number of enlisted soldiers, as well as specific individuals that were responsible for peace time affairs at home and others that were only a part of the army if an emergency should arise, specifically through the reserve.

Not only do the US Army components divide with these three adaptations, but also are divided with specific branches in each of the components. These are divided by levels of defense and also include branches that are in charge of different types of defense. This ensures that each of the components is able to uphold the specific duties needed during both peaceful eras and during war time. Depending on the needs of the time, the different US Army components will be called upon with the duties that are required by the sections to help with national and international affairs.

Beyond this main US Army components are also extra forces that are often used for the defense of the national US system. There are various state defense forces that are supported through the national guard, for instance, to assist with specific needs or emergencies. There are also components that include unorganized militias. These soldiers are similar to the reserve army and will be used if there is an extreme emergency or war time situation.

The organization of the various US Army components is one that has continued to expand from World War I to ensure that every soldier is able to uphold a specific placement within the military. The different components that are organized have grown and changed according to the needs of the time, as well as the duties that are required by different individuals. This has led to a change in duties and sections, and also includes the ability to meet conflict that may be a part of the national or international affairs of the time.

The first rule that is defined with the US military order of rank is defined by the branch that is called into duty. There are three main branches in the US, including the army, air force and marine corp. These are further divided by the duties that are assigned within the branches. For instance, the army has three main components, including the active duty section, regular army and two reserves. The difference between these is based on how often each of the soldiers is called to work as well as what is required for their active duties. These branches also have different divisions and units, each which is located in a different sector of the United States and which is responsible for specific types of duties and training.

Within each of the units and divisions are orders of rank that are held by groups of individuals to define the active duties that are assigned in times of both peace and war. In order to achieve a specific US military order of rank, an individual has to show specific qualities, such as leadership qualities or training. These are typically given when one begins to put in a specific amount of time in the military, with responsibilities that continue to change according to how an individual performs.

In all three divisions of the military, are similar ranking systems that are used. The difference between this is based on the units that one is assigned to, which means that the specific duties will differ according to the assignment that the units have. The three US military order of rank systems begins with enlisted personnel that have just entered into the army. This continues with warrant officers that hold alternative leadership roles. This specific ranking is not available in the air force as a main component for ranking. The third and highest set of roles is the set of commissioned officers, and includes lieutenants, captains and generals that are assigned to specific duties.

Within each of the three order of ranks, are different levels in which an individual can work up to. For instance, at the enlisted role, every soldier starts off at the lowest level of being a private. As they build their expertise and experience through time and training, they are able to gather ranking with the highest in enlisted personnel being the sergeant major. As this moves up in ranking, new duties are assigned to those that are carrying through with their tasks, as well as alternative training that is provided or requested and offered to others.

The specifics that are a part of the US military order of rank offers organization and structure throughout the different military units. By creating the divisions and subdivisions, there is the ability to keep a sense of leadership with the different duties assigned. This also allows each of the individuals in the military to understand what types of commands are needed and available to those in the military. The result is a completion to duties, training and expectations at every level.

There are three areas of the military that use abbreviations for military rank. The army, air force and marine corp. all have different abbreviations that are used instead of the complete name for the rank that one holds. The difference in abbreviations for military rank between these divisions of the military is based on what defines the name as well as how it is used to associate with others for levels of leadership.

In the army, the military rank is typically divided by the level of leadership that one holds as well as the level of importance and authority that one holds. You will notice the abbreviations first by the level or rank that is held. There are three ranks in the army division, including enlisted, warrant officers and officers. At the enlisted level, you will notice abbreviations according to the rank. For instance, a private will be abbreviated as PVT. At the warrant officer level, all abbreviations will include a WO plus the number in rank. The officer level, which is the highest, uses similar abbreviations for military rank, ranging from 2nd Lieutenant (2LT) to the General (GEN). By knowing the basic ranking names, you can define one’s credentials and the position they hold in the army.

These same rankings can be seen in the marine corp. While there are different divisions and placement of leaders by association of role and name, the shorter letters are still defined in the same way. The difference between these divisions and the Air Force divisions are based on the name of the position as well as the responsibility that is held. It is also known that the Air Force does not have a division for warrant officers, making some of the roles and number in ranking has a different number.

Another set of abbreviations for military rank that are considered is divided according to the area in which one resides. There are several military individuals that have separate divisions according to their unit as well as medals or awards that have been received by the individual. For instance, if an individual is a sharp shooter, then the abbreviation SS will be added into their unit and abbreviation listing. If they have won an award, then the same abbreviations may be used. For instance, a second SS may mean silver star, depending on the position of the individual, their rank or the actions taken during various times of combat or in peace time.

To understand the abbreviations for military rank, it is essential to understand the divisions and roles of those in the military first. From this, you can determine the abbreviations and roles of individuals. Adding in units, divisions and medals or awards to this also provide an extra determination in understanding the role of an individual in the military, what their responsibilities were and the actions that were taken during their time of service.

The forms of leadership within the army include three main ranks that individuals are divided by, including the enlisted rank, warrant officers and officers. Each of these is expected to hold certain duties and have several individuals within each ranking. These individuals are expected to provide specific duties while taking on forms of leadership and training to continue to move forward within the rank. When upholding these responsibilities, individuals have the ability to move up in ranking in the army. This is typically seen through performance levels shown over a specific time period, combined with roles that each individual holds during their time of duty.

The enlisted rank is the first division within the army, which every soldier automatically enters into when joining the army. The lowest level within this is the private, and consists of new soldiers that have begun their training. The responsibilities at this level include taking orders from others in the division as well as following the rules within the army. As this moves up through rank, the ability to command squads of lower divisions are available, such as through sergeant rank. The highest division in the enlisted rank in the army is the sergeant major of the army. This individual sees over other officers and works as a consultant to the chief of staff in the higher division.

The second rank in the army is the warrant officer. The first level in this ranking is a warrant officer I. In order to maintain this title, there is the need to be appointed by the Secretary of the Army. These individuals work to support various operations for battle and also assist in training and development within the army. This set of ranks in the army continues with the same types of duties, only holding higher responsibilities and levels of leadership. At this level, an individual can move up to a Chief Warrant Officer 5. The difference in this rank is dependent on the training assistance that is provided. This individual is responsible for new leadership roles to assist others that are in this branch.

The third ranks in the army consist of officers, and are inclusive of leaders that hold titles of lieutenants, captains, majors, colonels and generals. The second lieutenant is the entry level leader with this rank and leads platoons of squads in various areas. As each rankings moves up, are more duties in leadership that are assigned, including everything from leading squads to instruction, ordering commands to others and coordinating various missions. The highest level in this rank is the General of the Army and is used only during war time to command specific maneuvers with armies of other nations.

With the various ranks in the armies, are several forms of leadership that are available. Each of these is divided according to roles and responsibilities and continues with training and tactical responsibilities that are needed to build strategies within the army. Each of the ranks in the army contains the ability to build into a new level of service and leadership while serving in the army.

The first marine division is based out of California and is a unit of the Marine Expeditionary Force. This is the oldest division in the military and is known for having several roles within one unit. The main concern of this division is to provide ground combat elements, also known as GCEs. There is also task oriented jobs to assist with various operations through various environments. This is followed by the second marine division, which is based out of North Carolina. This particular marine corp. division also supplies ground combat elements.

The third base for divisions is located in Okinaway Japan as an infantry division. This Third Marine Division includes a logistics group and expeditionary force as well with it’s first introduction being an outcome from needed combat during the Vietnam War. The 4th Marine Division, is a reserve that is based out of Louisiana and is also known as a ground combat element. However, the focus of this division is to provide training for combat and to keep levels of security and protection available in case of a war.

These main divisions within the marine corp. continue with the 5th and 6th divisions. While these two combat divisions are inactive, they are still recognized for the services provided during World War II. These divisions were implemented during war time to assist in battle and included a combination of infantry and combat troops that were used overseas. These provided alternative solutions during the war, which are no longer necessary as a part of active duty in the marine corp.

With the different divisions that are available are also specific organizational structures that are a part of each of the combat areas. It is through this that individuals are able to gain marine corps ranks. While each of these alters according to the main missions, others have been divided according to camps as well as the main function and role of that division. These are first divided into units, each which is responsible for a specific form of combat. This continues into marine corps ranks of various officers to ensure that times of war are provided with the correct responsibilities and actions by each of the combat units.

With the various placement of divisions available, are strategic arenas in which the military is able to operate from. Doing this has provided alternative ways of defense for the US military, while providing various individuals with different missions and alternatives for the needs of the military. Understanding the placement and roles of the divisions within the military is one that introduces you to the several roles and missions that are a part of the marine corp. and the marine corps ranks.

Enlisted personnel stand at the lowest point of reference for authority figures. Beginning the list are new recruits, or Privates. Privates are in fact an exception to the rule of corresponding insignia, as they are not presented with one upon entering Marine ranks. However, advancement from Private (PVT) to Private First Class (PFC) earns a single stripe. Subsequently, a promotion from PFC to Lance Corporal (LCPL) adds the symbol of two rifles intersected at the middle, shown just below the first given stripe. Similar to the United States Army, each level of promotion after this point comes with an additional stripe and reorientation of the overall design pattern. Advancement through the enlisted personnel for the Marine ranks takes place as follows: Private, Private First Class, Lance Corporal, Corporal, Sergeant, Staff Sergeant, Gunnery Sergeant, Master Sergeant, First Sergeant, Master Gunnery Sergeant, Sergeant Major and Sergeant Major of the Corps.

Warrant officers stand above enlisted personnel with reference to their level of authority. The terms describing this section of Marine Corps rank resemble the United States Army, yet again, in the simplicity of reference. For instance, the lowest level of authority begins with Warrant Officer 1 (WO) and continues on as follows: Chief Warrant Officer 2 (CWO2), Chief Warrant Officer 3 (CWO3), Chief Warrant Officer 4 (CWO4) and Chief Warrant Officer 5 (CWO5). Unlike the category for enlisted personnel, Marine Corps rank coincides with a metallic insignia. For WO, the corresponding insignia displays two red bars surrounded by a gold border. The CWO2 wears 3, smaller, red bars, also surrounded with a gold border. The CWO3′s 2-red bars are surrounded by a silver border in much the same way gold surrounds WO’s insignia. The CWO4′s insignia resembles CWO2′s insignia but replaces the gold border with a silver one. The CWO5′s insignia stands out among the rest in that there’s only a single, vertical, red stripe, which is surrounded by a silver border.

Commissioned officers take the highest level of authority and command responsibilities within the compilation of Marine ranks. The chain of authority among this category begins with the Second Lieutenant (2nd Lt), progresses to First Lieutenant (1st Lt) and proceeds as follows: Captain, Major, Lieutenant Colonel, Colonel, Brigadier General, Major General, Lieutenant General, and General. The insignia for commissioned officers is also metallic but unlike warrant officer’s insignia, each rank has its own particular design. For the 2nd Lt, the Marine Corps rank insignia is a single yellow bar. Following in suit, the 1st Lt’s insignia is a single silver bar. The Captain wears 2 silver bars, side-by-side. The Major bears an insignia of a 7-pointed gold symbol. The Lieutenant Colonel bears the same 7-point symbol but in silver, instead of gold. The Colonel bears the Marine ranks insignia of a bald eagle. The Brigadier General, Major General, Lieutenant General, and General all bear silver 5 pointed stars, in a row of 1, 2, 3 and 4, respectively.

Careers among Air Force Ranks

Of course, just because you’re a member of the Air Force, this doesn’t mean you’ll be flying a plane all the time. In contrast, most Air Force ranks and personnel perform jobs within the military on the ground. Civil affairs, technological positions, hospitality needs, medical personnel and security forces comprise a short list of the many career options available in the US Air Force Ranks.

Hierarchal-Chain of Command: US Air Force Ranks

US Air Force Ranks can be easily identified by splitting the divisions and hierarchal-chain of command into 2 categories, enlisted personnel and commissioned officers. Separating Air Force Ranks into these two categories allows us to get into detail about specific points of reference.

Air Force Rank: Enlisted Personnel

Unlike the US Army, the US Air Force Ranks do not have a category for Warrant Officers. Instead, the category for enlisted personnel begins with Airman Basic and extends through Chief Master Sergeant. Along the same lines, commissioned officers begin with Second Lieutenant and proceed through to the General of the Air Force.
The US Air Force ranks authority, responsibility and importance of the individual holding the position in order of least to greatest; thus, Airman Basic is an entry level position for Air Force ranks. Enlisted personnel would follow the chain of promotion from Airman Basic to Airman, Airman First Class, Senior Airman, Staff Sergeant, Technical Sergeant, Master Sergeant, First Sergeant, Senior Master Sergeant, Chief Master Sergeant and finally Chief Master Sergeant of the Air Force. As with most other divisions of the military the last among the US Air Force Ranks simply details an individual with respective authority in non-war times.

Air Force Rank: Commissioned Officers

Continuing with US Air Force ranks, we encounter the 2nd Lieutenant position as the starting point for commissioned officers, as promotion follows: 1st Lieutenant, Captain, Major, Lieutenant Colonel, Colonel, Brigadier General, Major General, Lieutenant General, General and General of the Air Force comprise the chain of command.

US Air Force Ranks and Insignias

US Air Force ranks are accompanied by different types of insignias as you move up in priority. For instance, an Airman Basic does not wear any insignia, when just entering their position. Upon promotion to Airman, the individual will bear the air force rank insignia of a single stripe or “wing” as the figure is bent solidly in the middle at the points of a star. As the individual moves through promotion and proceeds in air force rank, more stripes will be added to note their achievements and new position of authority, responsibility or importance. The Chief Master Sergeant of the Air Force will wear an air force rank insignia with 8 “wings” and the symbol of a star in the middle of 3 separated stripes. Along the way, when an individual reaches the status of Master Sergeant the “wings” will reflect from the original position of the first 5 and any additions from then on will accompany this set. At the point of this achievement, individuals will also receive a pendent, which will need to be worn on the collar and hat in addition to the insignia on the shoulder.

The US military rank system includes 7 branches, which are responsible for protecting the United States and serving in active duty during warring times. Some branches may work hand-in-hand with other divisions in order to complete their objectives; while others take a more specialized approach to service. Of the seven, there exist 3 main divisions, which are often referenced with the use of military rank abbreviations. The Army, Air Force and Marine Corps use military rank abbreviations frequently as a point of reference to the chain of command. US military ranks specify an individual’s level of importance, duties and authority throughout each of these divisions. 3 main categories provide a foundation for referencing the chain of command, enlisted personnel, warrant officers and commissioned officers. Commissioned officers take precedence over warrant officers and enlisted officers follows warrant officers.

Air Force stands apart from the Army and the Marine Corps military rank abbreviations in that it has no warrant officers to reference. Instead, the number of enlisted personnel is increased to fit about the same number of positions held in each other division.

US Military Ranks and Abbreviations for the Army

US military ranks and military rank abbreviations are handled differently with respect to each division. The Army begins with the lowest individuals in the chain of command, enlisted personnel. A Private or PVT marks the beginning of the list, PV2 follows and Private First Class or PFC closes the enlisted personnel category. A specialist (SPC) can be considered above a PFC but isn’t necessarily included in the category of enlisted personnel. Military rank abbreviations for the Army in respect to warrant officers are listed with the same level of authority as enlisted personnel and are as follows: Warrant Officer 1 through Warrant Officer 4 and ending with Master Warrant Officer 5 (WO1 through WO4 and WO5, respectively). The 2nd Lieutenant (2LT) opens the category for commissioned officers and General of the Army (GEN) ends the list.

US Military Ranks and Abbreviations for the Air Force

The Air Force uses completely different military rank abbreviations, as they label each of their positions and US military ranks separately. Enlisted personnel for the Air Force Begins with Airman Basic (AB), progresses to Airman (Amn), Airman First Class (A1C), progresses through the Sergeant (Sgt) ranks and ends with the Chief Master Sergeant (SMSgt). The Air Force does not assign any military ranks for the ‘warrant officers’ category. Instead, the list picks up with commissioned officers. The 2nd Lieutenant or 2d Lt Heads off the list, followed by the 1st Lieutenant or 1 st Lt. the Chief Master Sergeant, CCMSgt completes this category for the Air Force’s military rank abbreviations.

US Military Ranks and Abbreviations for the Marine Corps

The Marine Corps approaches rank in the same manner as the Army. Heading off the enlisted personnel is the Private or Pvt., following chains of command: Private First Class (PFC), Lance Corporal (LCpl), Corporal (Cpl), Sergeant (Sgt), Staff Sergeant (SSgt), Gunnery Sergeant (GySgt), Master Sergeant (MSgt), Sergeant Major (SgtMaj) and the Sergeant Major of the Marine Corps (SgtMajMC). The Marine Corps handles the category of warrant officers in much the same way as well, for instance the leading officer is the Chief Warrant Officer 5 CWO-5 and the lesser position among the ranks is Warrant Officer (WO-1). As for the commissioned officers, the order begins with the 2nd Lieutenant (2ndLt) and progresses to the Commandant of Marine Corps (Gen). The Marine Corps does not assign an unofficial rank for an individual of authority in non-war times. The ranks remain the same throughout peace and wartimes.

Commissioned officers sit among the top individuals in the chain of authority for Navy ranks. The following lists the chain of authority within this category from least to greatest: Ensign (ENS), Lieutenant Junior Grade (LTJG), Lieutenant (LT), Lieutenant Commander (LCDR), Commander (CDR), Captain (CAPT), Rear Admiral (RDML), Vice Admiral (VADM), Admiral (ADM), and Fleet Admiral (FADM). Commissioned officers within the highest order of Navy rank wear insignia similar to those of Marine Corps. The biggest difference in insignia for naval ranks pertains to the addition of pieces to be worn on the collar and cap. Each promotion in ranks adds a stripe to the additional pieces worn on the cap and collar. All Admiral Positions progress in the number of stars for their main insignia piece as their Navy rank becomes higher.

Warrant officers follow commissioned officers in the chain of command and are rather easy to refer to: Warrant Officer 1 (WO), Chief Warrant Officer 2 (CWO2), Chief Warrant Officer 3 (CWO3), and Chief Warrant Officer 4 (CWO4). The highest warrant officer, CWO4, wears navy rank insignia as metallic emblems. One emblem represents 2 silver bars surrounded by a blue border. The other is an elongated pentagon with a single stripe at the bottom, interrupted by a blue stripe. The Navy symbol of two anchors crossing at an intersection sits just above the single stripe on the bottom half.

Enlisted personnel follow commissioned officers and warrant officers within naval ranks. In order to advance through these positions, the individual will begin as a Seaman Recruit and become promoted in the following order: Seaman Recruit (SR), Seaman Apprentice (SA), Seaman (SN), Petty Officer 3rd Class (PO3), Petty Officer 2rd Class (PO2), Petty Officer 1rd Class (PO1), Chief Petty Officer (CPO), Senior Chief Petty Officer (SCPO), Master Chief Petty Officer (MCPO), and the Mst. Chief Petty Officer of the Navy. The SR, SA and SN wear Navy Rank insignia displaying two anchors crossed at an intersection and are presented with an additional stripe of honor as they advance through the ranks. PO3 through PO1 wear navy rank insignia of a bald eagle perched on the subsequent stripes of additional order in achievements for rank. They also wear a metallic emblem on other parts of the uniform. The CPO, SCPO, MCPO and Master Chief Petty Officer of the Navy wear a similar navy rank insignia to PO’s, with additional stars to represent rank. Instead of a red stripe as worn on PO’s insignia, these commissioned officers wear yellow stripes. These officers are also presented with a metallic symbol to wear on other parts of the uniform to further identify their achievements in progressing through the naval ranks.

The United States Naval Department employs nearly ½ a million individuals active in duty. There is a good sum of personnel “on call” in the Navy Reserve. For personnel “active” in duty, almost 80% comprise the naval ranks among enlisted personnel. Commissioned officers delegate 15% of the remaining individuals. As with the Army, there is a NROTC group of individuals dispersed throughout the country in high schools and universities.

The US military ranks system provides tiers of authoritative figures, delegation of responsibility and position of importance within a certain branch. Most branches refer to US military ranks with different terms to describe each tier of authority. Three general categories were created to help organize the separate tiers. The leading category in terms of authority is commissioned officers. The secondary category in terms of authority refers to warrant officers. And last, but not least among US army ranks are the enlisted personnel.

Ranks in the army are separated and filed in the order of smallest authority powers to largest authority powers. Enlisted personnel come first with regards to US army ranks. Military personnel of entry level authority are referred to as Privates. Advancements through the chain of authority are as follows: Private First Class, Specialist, Corporal, Sergeant, Staff Sergeant, Sergeant First Class, Master Sergeant and First Sergeant.

The advancements through the category of warrant officers are much simpler in reference to naming, than enlisted personnel. For instance, the individual with the least authority in this category is referred to as Warrant officer. Subsequently, the following US army ranks are Chief Warrant Officer 2, Chief Warrant Officer 3, Chief Warrant Officer 4 and Master Warrant Officer 5.

Commissioned officers have the highest level of authority within the Army ranks. The positions of authority progress as follows: Second Lieutenant, First Lieutenant, Captain, Major, Lieutenant Colonel, Colonel, Brigadier General, Major General, Lieutenant General, General and General of the Army. In wartimes, the General of the Army does not assume the ultimate position of authority. Instead, the General determines the course of action in wartimes from within the US army ranks.

Army Rank Insignia

Each branch of the military wear specific insignia to display their position of authority and importance. Ranks in the army can be easily identified by looking at one’s army rank insignia.

A Private within US army ranks will wear the army rank insignia of a single, yellow stripe, shaped in a triangular fashion but missing the “bottom” portion of the triangle. This stripe is surrounded by a green border. For a Private First Class, another stripe is added to fix a convex “bottom” to the Private’s incomplete triangle as their army rank insignia. A Corporal wears two stripes in a similar fashion to the Private’s single stripe.

The Sergeant’s army rank insignia follows suit of the Private and Corporal but has a third strip added. The Staff Sergeant’s army rank insignia displays the Sergeant’s initial 3 stripes and adds a convex “bottom” to the last stripe of the original 3. A Sergeant First Class Army rank insignia resembles the Staff Sergeant’s insignia and adds an additional stripe below the convex, “bottom” of the triangle. The Master Sergeant follows suit by adding yet another stripe under the convex stripe. The Sergeant Major retains the same design as a Master Sergeants army rank insignia and displays their achievements by adding a star in the middle of the triangle. The Command Sergeant Major also retains the original design of the Sergeant Major’s insignia but a different symbol is used in the middle of the triangle.

The commissioned officers wear different styles of metallic emblems as their army rank insignia.
