Army Ranks
Company Grade Officers are Commissioned Army Officers who occupy the ranks of O-1 to O-3. Field Officers belong to the pay grades O-4 to O-6. General Officers are those in pay grades O-7 and above.
However, regardless of pay grade, every officer discharges a significant role in fulfilling the army's mission. That is why the ranks are more than an indication of pay grade. They establish a leadership framework within which each officer knows the level of expertise expected at each rank and the accompanying responsibility and authority.
Second Lieutenant
The key objective of this entry-level rank of Commissioned Army Officers is to gain leadership qualities. Second Lieutenants develop their primary branch by attending introductory sessions, after which the majority are assigned their first duty while some go for ranger or airborne training.
First Lieutenant
By the time officers progress to becoming Second Lieutenant, usually within two years, they have polished the traits required to excel in a military career. They apply their earlier training and learn how to lead troops in their new role.
Captain or Company Commander
The next rank you may rise to, typically in about four years, is that of Captain or Company Commander, who takes charge of over 100 soldiers. Units under a Captain can independently perform a battlefield function. You must choose and qualify for a specific function during the Captain phase. You must also attend the Officer Advanced Course and later the Combined Arms and Services Staff School (CAS3), which trains you to be appointed Field Grade Staff Officer.
Major
A Captain is promoted to Major in about 11 years, indicating a significant step forward in your career. As a key staff officer, you deal with personnel, intelligence, operations, or logistics and receive assignments which help you use your existing skill set and grow professionally. You gain further expertise in your branch and specific functional area. Some officers are selected to attend Command and General Staff College or civilian schools.
Lieutenant Colonel or Battalion Commander
Promotion to Lieutenant Colonel can take about 17 years and puts you in charge of leading hundreds of soldiers in a battalion. Exceptional achievements can lead to higher and more challenging roles. Some officers are selected for the Army War College for further expertise in their field.
Colonel
Promotion to Colonel happens after completing 22 years of army service, making you a top executive. As a Brigade Commander, you are in charge of thousands of soldiers or the director of a large staff. This phase gives your senior responsibility and fully uses your expertise and leadership, testing them under extreme conditions.
General Officers
Achieving the rank of General takes close to 25 years, and only those who demonstrate exemplary executive and leadership skills may be chosen to become the CEOs of the army. Fulfilling their senior-level responsibilities, they must maintain a highly efficient and effective army.
Types of Commissioned Army Officers
Combat Special Officers oversee combat activities, serve as combat leaders and direct military operations. They are in charge of tanks, other armoured assault vehicles, artillery systems, special operations, or infantry units, also overseeing naval surface warfare and submarine warfare officers, combat pilots, and aircrews.
Engineering, Science, and Technical Officers work in scientific and professional roles, such as atmospheric scientists, meteorologists, physical or biological scientists, social scientists, and attorneys. Their work contributes to army operations. For instance, weather studies by meteorologists assist flight path planning for military aircraft.
Executive, Administrative, and Managerial Officers manage administrative tasks in the armed forces.
Healthcare Officers, including physicians, physician assistants, nurses, optometrists, dentists, psychologists, physical therapists and more, provide expert medical diagnosis, treatment, therapy, rehabilitative care, and other forms of healthcare to military personnel.

Media and Public Affairs Officers handle the production, development and presentation of information, news releases or events for the benefit of the public and the military and respond to relevant public queries. They plan, develop, and direct the activities of military bands and produce video, television and radio broadcast content for various purposes.
Protective Service Officers are in charge of the safety and protection of individuals and property on military vehicles, aircraft, vessels, or bases. They may work as emergency management officers who develop procedures in preparation for any disaster or as law enforcement and security officers who enforce laws and conduct criminal investigations on military bases.
Support Services Officers address military activities in key functional areas, such as logistics, transportation, and the supply and distribution of food supplies and other materials. Purchasing and contracting managers negotiate and monitor purchase contracts for services and supplies from the private sector.
Transportation Officers coordinate the safe transport of military personnel and equipment over the ground, water, and air. They may be in charge of commanding or operating army vehicles, aircraft or ships and may work as navigators, pilots, or ships’ engineers.
The Officer Education System
Among the various courses available at OES, the Basic Officer Leader Course helps develop junior-level officers into competent and confident leaders equipped with a warrior ethos and with the skills necessary to lead small units.
The Captain's Career Course trains Company Grade Officers to command at the company level and appropriately service staff positions in brigades and battalions.
Intermediate Level Education prepares Majors to lead operations in join, interagency or international settings.
The School of Advanced Military Studies provides graduate-level education in military art and science to help officers evolve as Commanders and Generals. The focus is on solving intricate military problems in times of peace and war in joint, multinational, and interagency scenarios.
The School for Command Preparation provides new commanders of brigades and battalions with opportunities to develop leadership skills.
The Senior Service College helps selected senior Commissioned Army Officers, civilians, and international leaders become responsible for strategic leadership.
Rank, Insignia & Pay Grade
Ranks are levels in the hierarchical structure of the military or another armed force. The insignia that service members wear on their uniform collars or shoulders represent ranks and include emblems such as chevrons, bars, oak leaves or stars. A service branch represents their pay grades using a letter and a number, such as O-1 to O-10 for Commissioned Army Officers.
Second Lieutenants in the US army wear a single gold bar, First Lieutenants wear one silver bar, and Captains wear two silver bars. A gold oak leaf signifies a Major and a silver oak leaf a Lieutenant Colonel. A Colonel sports a silver eagle. Then begin the star insignia for the Generals, one for a Brigadier General, two for a Major General, three for a Lieutenant General, and four for the General, the Chief of Staff.
