What is Military Occupational Specialty (MOS)?
Military Occupational Specialty (MOS) is a code or identifier assigned to a soldier, sailor, airman, or Marine that denotes their specific job or position within the military. In other words, an individual’s MOS defines their assigned role, responsibilities, and duties within the military structure. Each MOS is designated by a unique number or code, which is usually preceded by a letter identifying the branch of the military (e.g., AR for Army, NM for Navy, AF for Air Force, and MC for Marine Corps).
Purpose of MOS
The primary purpose of MOS is to assign personnel to specific jobs within the military, ensuring that each individual is utilized optimally to achieve the overall mission objectives. The concept of MOS is rooted in the idea that each personnel has unique skills, education, and training, and that these attributes can be leveraged to fulfill critical roles within the military structure.
Categories of MOS
MOSs can be broadly categorized into six main groups:
• Combat Arms: These include jobs that involve direct engagement with the enemy, such as infantry, artillery, and armor.
• Combat Support: These are jobs that provide support to combat units, such as intelligence, logistics, and communications.
• Support Services: These include administrative, medical, and non-combat support roles, such as human resources, finance, and chaplains.
• Healthcare: These are healthcare-related jobs, including nurses, doctors, and dentists.
• Sustainment: These roles involve maintaining and supporting equipment, facilities, and logistics, such as maintenance and supply chain management.
• Technical and Trade Support: These jobs involve skills and expertise in specific fields, such as mechanics, electricians, and aviation maintenance.
Hierarchy of MOS
Within each category, MOSs are hierarchical, with more senior personnel holding higher-level designators. For example:
| MOS | Job Title | Rank |
|---|---|---|
| 11B | Infantryman | E4 (Corporal) |
| 11B20 | Infantry Squad Leader | E5 (Sergeant) |
| 11B40 | Infantry Platoon Sergeant | E6 (Staff Sergeant) |
The hierarchy is based on individual performance, experience, and training, with higher-ranked personnel typically holding more significant responsibilities and authority.
How to get an MOS
Individuals can opt for a specific MOS or be assigned one based on their skills, education, and training. To acquire an MOS, individuals usually undergo:
• MOS Training: This may involve formal education, online courses, or on-the-job training.
• Assessment and Evaluation: Personnel are evaluated based on their performance, aptitudes, and interests.
• Assignment: Based on the assessment, personnel are assigned to a specific MOS.
Transfer and Reassignment
Military personnel may request or be reassigned to a different MOS if:
• Transfer Opportunity: A new MOS opening becomes available.
• Reassignment: The personnel’s skills and training do not align with their current MOS.
• Enlistment Option: Junior personnel may choose to trade in their current MOS for a new one.
However, reassignment or transfer may require additional training and evaluation to ensure the personnel are adequately prepared for the new role.
Conclusion
In conclusion, an MOS is a critical identifier that defines an individual’s role within the military, outlining their responsibilities, and duties. Understanding the different categories, hierarchy, and process of acquiring an MOS is essential for military personnel to excel in their assignments and contribute to the successful execution of military missions.
