The United States Army utilizes a Military Occupational Specialty (MOS) system to classify its soldiers' roles and responsibilities. This intricate system ensures the right person is in the right job, maximizing efficiency and effectiveness across the diverse branches of the Army. Understanding the MOS system is crucial for both aspiring soldiers and those already serving. This guide offers an overview of the vast landscape of Army MOS codes.

Understanding the MOS System

The Army MOS code is a four-digit alphanumeric code. The first digit generally indicates the career field, while the subsequent digits provide further specialization within that field. For example, a 11B MOS represents an Infantryman, while a 11C indicates a Indirect Fire Infantryman. These numbers are not static; they change periodically based on the Army's evolving needs and technological advancements.
