Which set of phrases constitutes the comprehensive Air Force motto used to guide day-to-day behavior?

• A. Loyalty, Courage, and Duty.
• B. Respect, Integrity, and Excellence.
• C. Duty, Courage, Integrity.
• D. Integrity First, Service Before Self, Excellence In All We Do.

Answer: (D)

Integrity First, Service Before Self, Excellence In All We Do is the Air Force motto used to guide day-to-day behavior. Integrity First means choosing honesty and strong moral principles in every action, even when no one is watching. Service Before Self emphasizes prioritizing the mission and the welfare of the team over personal gain. Excellence In All We Do pushes you to meet high standards and continually improve in every task. Together, these three phrases form the official standard that shapes decisions, accountability, and conduct in training and daily duties. Other sets may include similar values, but they don’t present the complete, official trio that serves as the full guiding motto.
