Who commanded more troops than any Marine General?

General Robert E. Cushman commanded more troops than any Marine General, particularly during the Vietnam War when he was the Deputy Commander, Military Assistance Command, Vietnam (MACV). His leadership encompassed a significant number of personnel across various operations, reflecting the immense responsibility he held during a critical period in U.S. military history.

Cushman's experience and role in Vietnam placed him in charge of a vast number of forces, showcasing his strategic capabilities and the trust placed in him by the Marine Corps and the U.S. government. His actions during this time were pivotal in shaping the Marine Corps' approach to combat and operations in complex environments, establishing him as a noteworthy figure in Marine history.

The other generals listed have had significant commands, but none managed as large a force as Cushman did during that particular phase of the Marine Corps' operational history.
