Citation... For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving with Company E, in action against enemy aggressor forces at Hill 132, in the early morning hours. Manning 1 of the several listening posts covering approaches to the platoon area when the enemy commenced the attack, Pfc. Christianson quickly sent another marine to alert the rest of the platoon.

Without orders, he remained in his position and, with full knowledge that he would have slight chance of escape, fired relentlessly at oncoming hostile troops attacking furiously with rifles, automatic weapons, and incendiary grenades. Accounting for 7 enemy dead in the immediate vicinity before his position was overrun and he himself fatally struck down, Pfc. Christianson, by his superb courage, valiant fighting spirit, and devotion to duty, was responsible for allowing the rest of the platoon time to man positions, build up a stronger defense on that flank, and repel the attack with 41 of the enemy destroyed, many more wounded, and 3 taken prisoner. His self-sacrificing actions in the face of overwhelming odds sustain and enhance the finest traditions of the U.S. Naval Service. Pfc. Christianson gallantly gave his life for his country.
