Citation... For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty as a flamethrower operator in action against enemy Japanese forces on Okinawa Shima in the Rykuyu Islands, 7 May 1945. Quick to take action when his company was pinned down in a valley and suffered resultant heavy casualties under blanketing machinegun fire emanating from a high ridge to the front, Pfc. Schwab, unable to flank the enemy emplacement because of steep cliffs on either side, advanced up the face of the ridge in bold defiance of the intense barrage and, skillfully directing the fire of his flamethrower, quickly demolished the hostile gun position, thereby enabling his company to occupy the ridge.

Suddenly a second enemy machinegun opened fire, killing and wounding several marines with its initial bursts. Estimating with split-second decision the tactical difficulties confronting his comrades, Pfc. Schwab elected to continue his l-man assault despite a diminished supply of fuel for his flamethrower. Cool and indomitable, he moved forward in the face of a direct concentration of hostile fire, relentlessly closed the enemy position and attacked. Although severely wounded by a final vicious blast from the enemy weapon, Pfc. Schwab had succeeded in destroying 2 highly strategic Japanese gun positions during a critical stage of the operation and, by his dauntless, single-handed efforts, had materially furthered the advance of his company. His aggressive initiative, outstanding valor and professional skill throughout the bitter conflict sustain and enhance the highest traditions of the U.S. Naval Service.
