The Headquarters Marine Corps organization is divided into (from largest to smallest) Departments (Commands), Divisions, Branches, Sections, and Units.
Each organization is identified by a unique Organization Name and Organization Code (wherever possible, we will add the organization code in parentheses after the organization name).
Many organizations also have a nickname or acronym by which they are known. This can easily become confusing to an employee who is new to the Marine Corps.
