John Walton Collier (April 3, 1929 – September 19, 1950) was a soldier in the United States Army during the Korean War.

While engaged in an assault on a strategic ridge strongly defended by a fanatical enemy, the leading elements of his company encountered intense automatic weapons and grenade fire.

Collier and 3 comrades volunteered and moved forward to neutralize an enemy machine gun position which was hampering the company's advance, but they were twice repulsed.

Shouting a warning to his comrades, he, selflessly and unhesitatingly, threw himself upon the grenade and smothered its explosion with his body.

Collier's supreme, personal bravery, consummate gallantry, and noble self-sacrifice reflect untold glory upon himself and uphold the honored traditions of the military service.
