Stationed in the front lines, Corporal Berry manned his weapon with alert readiness as he maintained a constant vigil with other members of his gun crew during the hazardous night hours. When infiltrating Japanese soldiers launched a surprise attack shortly after midnight in an attempt to overrun his position, he engaged in a pitched hand-grenade duel, returning the dangerous weapons with prompt and deadly accuracy until an enemy grenade landed in the foxhole. Determined to save his comrades, he unhesitatingly chose to sacrifice himself and immediately dived on the deadly missile, absorbing the shattering violence of the exploding charge in his own body and protecting the others from serious injury.
As he jumped to his feet 10 yards from the gun and charged forward, machine gun fire tore through his camouflage robe and a rifle bullet seared a 10-inch gash across his back sending him spinning 15 yards down hill into the snow. When the indomitable sergeant sprang to his feet to renew his 1-man assault, a German egg grenade landed beside him. He kicked it aside, and as it exploded 5 yards away, shot and killed the German machine gunner and assistant gunner. His carbine empty, he jumped into the emplacement and hauled out the third member of the gun crew by the collar.
