Which is one of the objectives of the Marine Corps promotion system?

The objective of maintaining the needed strength in each grade and Military Occupational Specialty (MOS) is fundamental to the Marine Corps promotion system. This approach ensures that the right number of personnel is available across various ranks and specialties to effectively meet operational demands and mission requirements. By aligning promotions with the needs of the Corps, it promotes readiness and enables the organization to function efficiently.

Promoting based solely on completion of training and education courses might not accurately reflect the overall capabilities required for success in a particular role. Similarly, ensuring that all Marines receive accelerated promotions would undermine the merit-based aspects of the promotion system, as it is crucial to recognize and reward performance and capability. Lastly, promoting Marines who do not perform satisfactorily does not uphold the standards necessary for maintaining an effective and professional force. Therefore, keeping the required strength in each grade and MOS is vital for maintaining a balanced and proficient Marine Corps.
