Step-by-step explanation:
The best description of General George Marshall's accomplishments during World War II would be that he commanded more than eight million soldiers as chief of staff of the U.S. Army. As one of the highest-ranking officials in the United States military at the time, his role was primarily organizational and strategic, rather than a direct field commanding role.
General Marshall was a central figure in organizing, commanding, and coordinating U.S. military efforts. He played a crucial role in planning and executing operations in both European and Pacific theatres. However, he did not lead U.S. forces in North Africa or command the forces at Normandy on D-Day; these roles were fulfilled by other distinguished generals.
