Army Career Fields

When Cadets reach their final year in the ROTC program, they order their branch choices by priority to determine their Army specialty.  Their selections are sent before the accessions board, which convenes in the fall.  Cadets receive their branch selections and begin to prepare for their new Army careers.  Below are the Army branches:


Adjutant General Corps

Basic Officer Leadership Course (BOLC) III: FT Jackson, SC


Officers in the Adjutant General's (AG) Corps serve at all organization levels of the Army where they plan, develop, and operate the Army's personnel management support systems; a vital responsibility in both peace and war.  Personnel systems include all life cycle functions such as personnel requisitioning, reassignments, evaluations, promotions, awards and decorations, reenlistment, casualty reporting, strength accounting, and replacement operations.  Administrative systems management includes courier and postal services.  The Army's Adjutants General shoulder a huge amount of responsibility for the smooth running of day to day Army operations.

The Quartermaster (QM) Corps offers a broad spectrum of opportunities. The QM Corps Officers plan and direct the activities of Army units and organizations engaged in the acquisition, receipt, storage, preservation, and issue of equipment, repair parts, fortification/construction material, subsistence, petroleum products, water, and other general supplies.  QM Officers must be both meticulous in their record keeping and far-sighted in their planning for future needs.

Signal Corps


Signal Corps (SC) Officers must blend together combat leadership skills and technical proficiency as they plan and manage information systems that support the command and control of the Army's forces.

Special Forces


Special Forces (SF) is a non-accession branch (eligible after promotion to Captain, or completion of Officer Advance Course) which encompasses positions concerned with the employment of highly specialized Army units and elements to accomplish specific missions throughout the levels of warfare.  They conduct the missions of unconventional warfare, foreign internal defense, direct action, strategic reconnaissance, and counterterrorism.  SF unit members are airborne qualified, language trained and area oriented.  Since potential missions are worldwide, soldiers train in forest, desert, mountain, arctic, jungle, and urban environments.

Transportation Corps


 "Nothing Happens Until Something Moves."  No matter how deadly a unit's firepower, it has no effect on the enemy unless that unit can get to the battlefield.  The monumental task of moving the Army from one place to another falls upon the Transportation Corps (TC), encompassing those positions related to the multi-modal movement of personnel and cargo over land, sea, and air, anywhere in the world.

Career Progression:

An Army Officer's career is generally a series of 2 and 3 year assignments, each one preparing you for the next.  Personal abilities and preferences affect the choices a person makes, so there is no one career blueprint. There is, however, a general progression most Officers' careers follow.

Getting Promoted:

One of the most attractive aspects of being an Army Officer is the structured promotion system.  The promotion system is designed to help both the Army and the Officer.  The system design enables the best Officers to reach positions of most importance and highest responsibility.  From an individual Officer's point of view, the promotion system assures qualified person advancement after a certain time.  In other words, your career can never get endlessly mired at middle management.  Your performance is reviewed on a regular basis during rating periods.  You will be told you are being rated, and told what is expected of you during this period.  We think this process is more than fair, and that it gives every Officer a real chance to be at his or her best.

The Army Rank Progression:

Lieutenant (2LT & 1LT): 

Once a Cadet graduates, he or she is commissioned as a Second Lieutenant (2LT). The first thing a young Officer does is develop in his or her primary branch by attending the Basic Officer Leadership Course (BOLC III).  BOLC III is branch specific, and is the phase where an Officer learns his or her Army specialty.   After BOLC III, some Officers opt for Airborne or Ranger training (or both).  But most go right to their first duty assignment.  Progressing from 2LT to First Lieutenant (1LT), the young Officer applies his or her training and develops his or her leadership abilities.  In fact, learning how to lead troops is the key objective of this phase.  Promotion to 1LT takes about 18 months.

Captain (CPT):  

A lot happens while you are a Captain.  The most important thing is to get experience as a Company Commander (or Battery Commander for Artillery Officers).  A Company Commander is normally in charge of over 100 soldiers.  Command experience, obviously, is a valuable resource throughout a career.  During this phase, you attend the Captain's Career Course (CCC).  Additional training during the Captain phase is your opportunity to become more valuable to the Army, since this is when you choose and begin to become qualified in a functional area.  Promotion to Captain takes about 4 years.

Major (MAJ): 

Promotion to Major signals a big step in your career.  You have become a key staff Officer in charge of such areas as Personnel, Intelligence, Operations, or Logistics.  You will be given new assignments which permit you to use previously developed skills, as well as expand your overall professional development.  The objective here is to develop further in your branch, and continue development in your functional area.  During this phase, you attend the Intermediate Level Education (ILE) course.  Some Officers are selected for Command and General Staff College and or given the opportunity to attend civilian schools.  Promotion to Major takes about 10 years.

Lieutenant Colonel (LTC): 

Your assignment might be as a Battalion Commander in charge of hundreds of soldiers or a General Staff Officer in a Division or Corps.  Outstanding performance will merit more and more challenging positions.  Some Officers are selected for the Army War College, where they become experts at their profession.  Promotion to Lieutenant Colonel takes about 16 years.

Colonel (COL): 

At this phase in your military career, the Army takes maximum advantage of your talents.  This means you will be assigned as a Brigade Commander in charge of thousands of soldiers or director of a large staff.  Your technical skills and accumulated executive talents will be put to the test.  This is the senior level of responsibility.  You are a top executive.  Promotion to Colonel takes about 22 years.

General Officer (Brigadier General; Major General; Lieutenant General; and General)

Officers who demonstrate extraordinary leadership and executive abilities are selected to become General Officers; the CEO's of the Army.  They do nothing less than run the Army.  From Division Commanders to Post Commanders to high level staff positions, General Officers are responsible for maintaining an efficient and effective Army. Promotion to General takes about 25 years.
