Which of the following is a requirement for a Marine to qualify for the Meritorious CPL Program?

To qualify for the Meritorious Corporal Program, a Marine must be recommended by their commanding officer. This recommendation is essential because the program is designed to recognize outstanding performance and leadership potential among Marines. The commanding officer's assessment is crucial, as it reflects their direct observation of the Marine's capabilities, work ethic, and overall contributions to the unit and the Marine Corps.

While other options may seem relevant, they do not fulfill the specific requirement for this program. For instance, there isn’t a mandatory training course that all candidates must complete, nor is there a requirement for a Marine to have served for a particular duration like five years. Additionally, holding a high school diploma is also not a prerequisite to being considered for the program. The necessity of a commanding officer's recommendation highlights the program's focus on recognized merit and leadership potential within the organizational structure of the Marine Corps.
