US Military Chain of Command and Army Basic Knowledge Practice Test

The main idea is that the Commander in Chief of the U.S. Armed Forces, which includes the Air Force, is the sitting President of the United States. The President has the ultimate authority over military operations and sets military policy, with the Secretary of Defense and the Joint Chiefs operating under that top command. So the person identified as Commander in Chief is the one who is serving as President at the time. In this context, that was Donald Trump, which is why that option aligns with the role. The others listed—Obama and Biden—were presidents at different times, and Pence is the Vice President, who does not hold the title of Commander in Chief.
