What is the motto of the U.S. Army?

• A. Duty First
• B. This We Serve
• C. Always Ready
• D. This We'll Defend

Answer: (D)

Defending the nation and the Constitution is the Army’s enduring purpose, and the motto that embodies that pledge is This We'll Defend. This phrase is the official Army motto and is even inscribed on the Army coat of arms, signaling a formal, lifelong commitment shared by every Soldier. The contraction emphasizes unity and collective responsibility—the idea that the entire Army stands together to protect the country against all enemies, foreign and domestic. The other options aren’t the Army’s official motto, so they don’t represent the Army’s formal pledge the way This We'll Defend does.
