Who is recognized as the Sergeant Major of the Army?

The correct answer is the current and most recognized Sergeant Major of the Army, Michael A. Grinston. He represents the highest enlisted position in the U.S. Army and serves as a key advisor to the Chief of Staff of the Army on matters concerning the enlisted force. Grinston has held this position since July 2019, focusing on the well-being of soldiers, promoting professional development, and ensuring that the voice of the enlisted ranks is heard at all echelons of leadership.

The other individuals listed have served as Sergeant Major of the Army, but they are not the current holder of that position. Kenneth O. Preston served earlier and was notable for his time during the Army's operations in Iraq and Afghanistan. Raymond F. Chandler and Daniel A. Dailey also had significant impacts during their respective tenures, contributing to various initiatives and improvements for enlisted soldiers. However, none of these former Sergeants Major of the Army hold the current position, which is vital for understanding the correct hierarchy and leadership within the U.S. Army.
