Who currently holds the position of Secretary of the Army?

Ryan McCarthy served as the 24th Secretary of the Army from July 2019 until January 2021. He was responsible for overseeing all aspects of the Army's operations, personnel, and resource management. His role included ensuring that the Army was prepared for a variety of missions, managing budgetary concerns, and implementing policies affecting soldiers and civilian employees. The responsibilities of the Secretary of the Army make it essential for someone in that position to have a clear understanding of the Army's operational needs and develop strategies for the future.

Given the context, it's important to recognize that Dr. Mark Esper and General Dunford served in different capacities during their time in military leadership. Esper was the Secretary of Defense following his time as Secretary of the Army, and General Dunford held various high-level command positions, including Chairman of the Joint Chiefs of Staff, but not as Secretary of the Army. General McConville is the current Chief of Staff of the Army, a position separate from that of the Secretary of the Army. These distinctions clarify why Ryan McCarthy is the correct answer for this question regarding the Secretary of the Army's position during his tenure.
