<P> The term was picked up by United States Marine Corps Major Evans Carlson from his New Zealand friend, Rewi Alley, one of the founders of the Chinese Industrial Cooperatives . Carlson explained in a 1943 interview: "I was trying to build up the same sort of working spirit I had seen in China where all the soldiers dedicated themselves to one idea and worked together to put that idea over . I told the boys about it again and again . I told them of the motto of the Chinese Cooperatives, Gung Ho . It means Work Together - Work in Harmony ..." </P> <P> Later Carlson used gung - ho during his (unconventional) command of the 2nd Marine Raider Battalion . From there, it spread throughout the U.S. Marine Corps (hence the association between the two), where it was used as an expression of spirit and into American society as a whole when the phrase became the title of a 1943 war film, Gung Ho!, about the 2nd Raider Battalion's raid on Makin Island in 1942 . </P>

Where does the phrase gung ho come from
