Who holds the position of Sergeant Major of the Army?

The position of Sergeant Major of the Army (SMA) is the highest-ranking enlisted soldier in the United States Army, providing leadership and guidance to all enlisted personnel. The correct answer indicates that SMA Dan Dailey held this prestigious position. He served as the 15th Sergeant Major of the Army from January 2015 to January 2018. During his tenure, he focused on improving soldier morale and welfare, as well as addressing issues such as professionalism and discipline within the ranks.

The other individuals listed do not hold the position of Sergeant Major of the Army. General Mark Milley is a general officer and, as of October 2023, serves as the Chairman of the Joint Chiefs of Staff. Honorable Robert M. Speer served as the Acting Secretary of the Army, and Donald Trump, as a former President, does not have any military rank or position within the Army hierarchy. Given the responsibilities and context of the SMA role, SMA Dan Dailey is recognized for his contributions and leadership during his time in this position, making the selection of him as the correct answer apt.
