Which of the following is NOT a requirement for personnel working with the president?

The requirement for personnel working with the president emphasizes loyalty, citizenship, and a record of satisfactory performance, but military experience is not mandated. While having military experience might be beneficial or preferred in certain contexts or roles, it is not a formal requirement for everyone in the president's staff. Consequently, individuals can serve effectively in these positions based on their skills, educational background, and political acumen rather than their military history.

Therefore, military experience being excluded as a requirement allows for a more diverse range of qualifications and experiences among the personnel assisting the president, encompassing various fields such as law, diplomacy, public policy, and administration.
