The one-year tour of duty deprived units of experienced leadership. As one observer put it, "we were not in Vietnam for 10 years, but for one year 10 times." As a result, training programs were shortened. Some NCOs were referred to as "Shake 'N' Bake" to highlight their accelerated training. Unlike soldiers in World War II and Korea, there were no secure rear areas in which to get rest and relaxation. One unidentified soldier said to United Press International that there was nothing to do in Vietnam and therefore many of the men smoked marijuana. He said, "One of the biggest reasons that a lot of GIs do get high over here is there is nothing to do. This place is really a drag; it's a bore over here. Like right now sitting around here, we are getting loaded. Whereas, it doesn't really get you messed up; that's I guess the main reason why we smoke it."
