for extraordinary heroism as Commanding Officer of the Third Battalion, Third Marines, Third Marine Division, in action against enemy Japanese forces during the assault on enemy-held Guam, Marianas Islands, 21 through July 23, 1944. Realizing the absolute necessity of clearing the high ground in his sector for the protection of the beachhead, and deprived by casualties of sufficient troop leaders for his troop units, Lieutenant Colonel Houser personally led elements of his Battalion in continuous assaults against enemy positions, exposing himself time after time to hostile fire. After successfully leading his Battalion in the seizure of Chonito Cliff and observing that the left flank of his Battalion was being held up by strong Japanese resistance from Adelup Point, he proceeded to his leading elements despite wounds received in the previous action and, organizing a tank-infantry fighting group, led an assault on the hostile strong point. While exposed to enemy rifle, machine-gun, mortar and artillery fire, he maintained an aggressive attack until this strategic point was completely taken by his Battalion. Always cool and resourceful, Lieutenant Colonel Houser brilliantly led his men throughout this period until seriously wounded on July 23, while assaulting a particularly well dug-in and defended strong point holding up the advance. By his forcefulness, leadership and outstanding courage in the face of strong hostile resistance, he served as an example to his officers and men and was primarily responsible for clearing the Japanese forces from his sector. His unswerving devotion to duty throughout was in keeping with the highest traditions of the United States Naval Service.
