Ronald Eugene Rosser (October 24, 1929 – August 26, 2020) was a United States Army soldier who received the United States military's highest decoration, the Medal of Honor, for thrice attacking a hill alone, killing 13 enemies while wounded and carrying wounded comrades to safety one winter day in the Korean War.

He joined the United States Army as a paratrooper for the 82nd airborne division in 1946 at age 17 shortly after World War II for a three-year term of service.

After one of his brothers was killed in the early stages of the Korean War, he re-enlisted from Crooksville, Ohio, in 1951 as a way of getting revenge.

[3] On January 12, 1952, Rosser, by then a corporal, was acting as a forward observer with Company L's lead platoon during an assault on a heavily fortified hill near Ponggilli.

[1][2] Rosser returned to the United States in May 1952 and was formally presented with the Medal of Honor by President Harry Truman a month later, on June 27, 1952.

While assaulting heavily fortified enemy hill positions, Company L, 38th Infantry Regiment, was stopped by fierce automatic-weapons, small-arms, artillery, and mortar fire.

Rosser once again exhausted his ammunition, obtained a new supply, and returning to the hilltop a third time hurled grenades into the enemy positions.

After exhausting his ammunition he accompanied the withdrawing platoon, and though himself wounded, made several trips across open terrain still under enemy fire to help remove other men injured more seriously than himself.
