 Master Sergeant retired Juan Negron, enlisted in the U.S. Army in 1948 as an infantryman. He served as a dog-faced soldier during the Korean War with the only all-Hispanic unit, the 65th Infantry Regiment 3rd Infantry Division. Sergeant Juan E. Negron distinguished himself while serving as a member of Company L's 65th Infantry Regiment during combat operations against an armed enemy in Kama-iri, Korea, on April 25, 1951. Negron took up the most vulnerable position on his company's exposed right flank after an enemy force had overrun a section of the line. When notified that elements of his company were withdrawing, Negron refused to leave his exposed position, instead delivering withering fire at hostile troops who had broken through a roadblock. When the hostile troops approached his position, Negron accurately hurled hand grenades at short range, halting their attack. Negron held the position through the night while friendly forces organized and launched a counterattack. Master Sergeant Juan Negron retired from the U.S. Army in 1971 after 23 years of service.
