When his unit was pinned down by grazing fire from the enemy's strong mountain defense and command of the squad devolved on him with the wounding of its regular leader, he made frontal, one-man attacks through direct fire and knocked out two machine guns with grenades.

He arose into the withering fire, dived for the missile and smothered its blast with his body. By his swift, supremely heroic action Pfc. Munemori saved two of his men at the cost of his own life and did much to clear the path for his company's victorious advance.
