I was recently wondering where the term "gung ho" came from.
Communism!
a-hem.
Carlson was interesting. Some said he was a Communist. Marines said of him, "He may be red, but he sure ain't yellow!"
He met Edgar Snow in China and read Snow's Red Star Over China. This encounter led him to visit the Chinese communist troop headquarters in northern China, where he met Chinese Communist leaders such as Mao Zedong, Zhou Enlai and Deng Xiaoping. Traveling thousands of miles through the interior of China with the communist guerrillas, often on foot and horseback over the most hazardous terrain, he lived under the same primitive conditions. He was impressed by the tactics used by Chinese Communist guerrillas to fight Japanese troops.

A year later, in 1942, he was placed in command of the Second Marine Raider Battalion with the rank of lieutenant colonel, a new combat organization whose creation he influenced. The organization and discipline of the 2nd Raiders was modeled on that of the Communist Route Armies he had observed during his time in China. Because of his relationship with President Roosevelt and the president's son, Captain James Roosevelt, a Marine reserve captain who authored a letter to the Commandant of the Marine Corps proposing creation the Raiders, the Marine Corps authorized the creation of the Raiders despite misgivings about Carlson's philosophy.[1][2]
In the military there is a sharp caste-system divide between officers and enlisted personnel, and even experienced noncommissioned officers were expected to be subservient to even the newest, greenest second lieutenant. Carlson's experience in having gone back and forth between officer and enlisted status in both the Army and the Marine Corps convinced him that this was not in the best interests of the service. Carlson saw the Communist approach as superior. Leaders were expected to serve the unit and the fighters they led, not to be served. Responsibility, not privilege, would be the keyword for battalion leadership when the Second Raiders formed up. Using an egalitarian and team-building approach, Carlson promulgated a new way for senior NCOs to mentor junior officers and work with the officers for the betterment of the unit. Even more controversial in concept, Carlson gave his men "ethical indoctrination," designed to "give (his men) conviction through persuasion," describing for each man what he was fighting for and why.
