Sergeant Ross Franklin Gray (August 1, 1920 – February 27, 1945) was a United States Marine who posthumously received the Medal of Honor – the highest military honor of the United States – for his heroic service in the Battle of Iwo Jima during World War II, having single-handedly disarmed an entire mine field while under heavy enemy fire.

Private First Class Gray left for overseas duty on January 13, 1944, and landed at Kwajalein in the Marshall Islands where he took part in the Roi-Namur campaign.

He ascertained that the advance was held up by a series of enemy emplacements connected by covered communication trenches and fronted by a mine field.

Through a hail of enemy small arms fire, Sgt Gray cleared a path through the mine field up to the mouth of one of the fortifications, then returned to his own lines, where with three volunteers, he went back to the battalion dump and acquired twelve satchel charges.

Under covering fire from the three volunteers, Sgt Gray advanced up the path he had cleared and threw the charge into the enemy position in order to neutralize it.

For his personal valor, daring tactics, and tenacious perseverance in the face of extreme peril on February 21, Sgt Gray was posthumously awarded the Medal of Honor by President Harry S. Truman.

Sergeant Gray was initially buried in the 4th Marine Division Cemetery on Iwo Jima, but later his remains were returned to the United States for private burial in Woodstock, Alabama.
