What is an ADF value?

• A. Discipline
• B. Leadership
• C. Service
• D. Loyalty

Answer: (C)

An ADF value is a standard that shapes how you act on duty and in everyday life. Service is the commitment to the nation, the mission, and to your fellow personnel—doing what needs to be done, supporting others, and putting the greater good ahead of self-interest. It shows you’re willing to contribute, endure challenges, and work for the team and country even when it’s hard. That focus on duty to others and to the mission is exactly what recruiters look for, especially in OSB assessments, because it underpins reliable teamwork and responsible decision-making.

Discipline describes self-control and adherence to standards, which helps you live any value. Leadership is the ability to guide and influence others, a capability rather than a stated value. Loyalty is about allegiance, which supports the ethos but is not listed as a standalone value in the common framework. So, Service is the best fit because it directly expresses the obligation to serve the nation, the unit, and your mates.
