Army 11A MOS is the official designation of the military specialty, or job occupation, of an Infantry Officer.

Army Infantry Officers provide many different functions to a unit.

For this reason, they command the respect and attention of soldiers of all ranks and specialties.

Someone in Army 11A MOS is actively involved in all levels of command and combined armed forces during missions on the ground.

As a result, Infantry Officers develop skills to lead situations of attack, defense, or other specialty operations.

The Army Infantry is a significant component of the service branch and has a long and impressive history.

In this regard, the Army Infantry represents the main land combat force and core fighting strength of the military branch.

While the tendency is to only regard infantry soldiers during times of combat, they also provide many functions during peacetime.

Job Duties

The United States Army Infantry Division is one of its most integral components.

Accordingly, the range of job duties for Army 11A MOS is diverse, including:

  • Leading and controlling the Infantry and combined armed forces during land operations.
  • Coordinating employment of Infantry Soldiers at all levels of command, including multinational operations.
  • Developing infantry doctrine, organizations, and equipment unique to these operations.
  • Instructing Army infantry skills at service schools or combat training centers.

In certain situations, it’s not uncommon for Infantry Officers to command infantry and combined armed companies consisting of 200-300 soldiers.

The United States Army imposes certain requirements for every MOS (military occupation specialty).

Therefore, Army 11A MOS is no different in regard to education, skills, qualifications, and training requirements:


In general, the U.S. Army is open to any U.S. citizen 18 or older.

However, the requirements are usually more demanding for Army Officers compared to enlisted personnel.

Accordingly, most Army Officers are college graduates with at least a 4-year degree.

Some Army Officers pursue this college degree after they enlist while others join the military with this distinction thanks to college experience.

Additionally, the U.S. Army requires that Officers are between the ages of 18-34 years old.

The Armed Services Vocational Aptitude Battery (ASVAB) which is generally an entrance exam that every enlisted member takes is not mandatory for 11A MOS.

Nevertheless, there are numerous other requirements necessary to be eligible for the military specialty.


Army 11A MOS has a few stipulations. 

Eligible candidates must complete the Basic Officer Leadership Course (more details, below).

In addition to certification, prospective Army 11A MOS must be eligible for a Secret security clearance.

Next, like any potential military occupation, it never hurts to already possess some helpful skills.

For starters, leadership skills can be improved (like anything), but there are some qualities and characteristics that some possess more than others.

For example, being a leader requires discipline, confidence, intelligence, course, and taking initiative.

Soldiers lead by example not only with their words but also with their actions and conduct.

Generally, Army officers maintain a strong physical performance while also coping with intense mental pressures.

For this reason, leaders are quick on their feet and can live with the consequences of their decisions.

In the end, the respect and integrity of an Army officer are measured best by those who fall under his or her command.


The above requirements are not enough to transform a candidate into an Army 11A MOS.

Additionally, those entering the Army officer program must complete the Basic Officer Leadership Course (BOLC).

BOLC consists of two different stages with the first part of the course (BOLC I or BOLC A) traditionally done before being commissioned.

Then, once the Army officer has been commissioned, the soldier usually completes BOLC B.

The second Army leadership course is designed to emphasize leadership skills along with military tactics and technical competence with weapons and equipment.

As such, recruits are challenged both in the classroom and in the field during training exercises.

According to the U.S. Army, Officer recruits develop:

  • Defensive Operations
  • Situational Analysis
  • Strategy & Development

Meanwhile, Infantry Officers may also volunteer for Airborne and Ranger School or for specific developmental assignments.

These volunteer assignments are intended to further develop leadership skills and other training necessary to the military occupation.
