Capt. Ray began directing the reinforcement of the site. When an enemy position pinned down 3 of his men with a heavy volume of automatic weapons fire, he silenced the emplacement with a grenade and killed 4 Viet Cong with his rifle fire. As medics were moving a casualty toward a sheltered position, they began receiving intense hostile fire. While directing suppressive fire on the enemy position, Capt. Ray moved close enough to silence the enemy with a grenade. A few moments later Capt. Ray saw an enemy grenade land, unnoticed, near 2 of his men. Without hesitation or regard for his safety he dove between the grenade and the men, thus shielding them from the explosion while receiving wounds in his exposed feet and legs. He immediately sustained additional wounds in his legs from an enemy machinegun, but nevertheless he silenced the emplacement with another grenade. Although suffering great pain from his wounds, Capt. Ray continued to direct his men, providing the outstanding courage and leadership they vitally needed, and prevented their annihilation by successfully leading them from their surrounded position. Only after assuring that his platoon was no longer in immediate danger did he allow himself to be evacuated for medical treatment.
