Army enlisted MOS (Military Occupational Specialties) list

The Army makes up the largest military branch in the United States. There are numerous occupations, referred to as Military Occupational Specialties (MOSs), within the various branches of the military. Broken out into career management fields (CMFs), there are over 150 Army MOSs. Army Special Forces members, known for their elite status and the prestigious Green Beret they earn, play a critical role in training allied troops and executing high-stakes direct action missions globally.

Each MOS has its own set of responsibilities and required skills. For example, infantry soldiers are primarily responsible for engaging and defeating enemy ground troops, often collaborating with other military specialties to carry out combat missions.

Understanding Military Occupational Specialties

Definition and Purpose of MOS

A Military Occupational Specialty (MOS) is a specific job or career field within the United States armed forces. The MOS system categorizes and identifies the various roles available, ensuring that each service member is assigned to a position that matches their skills and training. This standardized system is crucial for the efficient operation of the military, as it helps in the organization and management of personnel. Each branch of the US military uses a similar system, though the designations and terminology may vary. The primary purpose of the MOS system is to streamline the assignment process, making it easier to place personnel in roles where they can be most effective. Whether you’re interested in becoming a combat engineering senior sergeant or an aircraft maintenance senior sergeant, the MOS system helps guide your career path.

Career Management Fields (CMFs)

Overview of CMFs

Career Management Fields (CMFs) are essential for organizing and managing military careers. Each CMF groups related Military Occupational Specialties (MOSs) into specific career fields or functional areas. This categorization helps in career development and advancement by providing a clear framework for progression. For instance, the Infantry CMF includes roles such as Infantryman (11B) and Indirect Fire Infantryman (11C), both of which are crucial for ground combat operations. By grouping related specialties, CMFs ensure that service members can develop their skills and advance within their chosen field, whether it’s in combat roles, technical positions, or support functions.
