Who is the current Commander-in-chief of the Army?

The correct understanding of who the Commander-in-Chief of the Army is rooted in the broader context of the U.S. military structure and government. The President of the United States serves as the Commander-in-Chief of the armed forces, which includes the Army. Donald Trump held the presidential office from January 20, 2017, to January 20, 2021. During this time, he had the statutory authority over the Army and all military branches.

It is important to note that while various military leaders and officials play critical roles in the operational command and management of the Army, ultimate authority rests with the elected President. The other individuals listed were either serving in different capacities or not holding the office of President during that timeframe. Hence, they do not fulfill the role of Commander-in-Chief.
