What award is presented for exemplary behavior, efficiency, and fidelity during active duty?

The Good Conduct Medal is awarded to recognize exemplary behavior, efficiency, and fidelity during active duty. This award emphasizes discipline and good conduct, which are essential qualities in a military setting. It serves as a formal acknowledgment of service members who maintain high standards of conduct and performance over a specified period. The criteria for receiving the medal often include a clean record during the service period and demonstrating a commitment to the responsibilities and duties of military life.

In contrast, other awards serve different purposes: The Medal of Valor honors acts of bravery, the Meritorious Service Medal is given for outstanding service, and the Achievement Medal recognizes specific achievements rather than overall conduct. Therefore, the Good Conduct Medal is distinct in its focus on behavior and fidelity, making it the appropriate choice for the question.
