20. Edwin Walker
General Edwin Walker’s career took a dramatic turn when he was relieved of his U.S. Army command in 1961 for actively promoting far-right political views to his troops. Walker’s outspoken activism, both during and after his military service, ignited fierce debate over the boundaries between military professionalism and political involvement. He became a controversial symbol of the risks involved when senior officers blur the line between service and partisanship (via Texas Monthly).
