Color poster printed on white paper shows an image of two soldiers standing back to back in a jungle setting. Text below the image reads "WAR IN A MAZE / Vietnam, 1969 / Because of the shortage of NCOs during the Vietnam War, first-term 'buck' sergeants, normally squad leaders, often found themselves in command of combat patrols. Many of these men were graduates of the Noncommissioned Officers Candidate Course. Known in the field as 'shake and bakes,' these instant NCOs quickly mastered the difficulties of warfighting in rugged terrain. Reliable radio communications gave them immediate access to fire power never before available to junior leaders. Here a patrol leader under attack calls his fire support center for assistance.
