WASHINGTON (Reuters) - Two years after his team came under heavy fire in an ambush in Afghanistan, former active duty Marine Corps Corporal Dakota Meyer will receive the Medal of Honor Thursday from President Barack Obama.

Meyer, 23, now serving as a sergeant in the Marine Corps Inactive Ready Reserve, will become the third living recipient of the Medal of Honor for actions in Iraq and Afghanistan, and the first Marine.

While on active duty, Meyer was twice deployed, serving in both Iraq and Afghanistan. It was his actions on September 8, 2009 as part of an embedded training team for which he is receiving the Medal of Honor, the nation's highest military decoration for valor.

Meyer was serving as a turret gunner and driver in Afghanistan and made several trips to rescue trapped U.S. and Afghan troops ambushed by rocket propelled grenades, mortars and machine gun fire, sustaining shrapnel wounds.

Meyer, who was born in Columbia, Kentucky, enlisted in the Marines in 2006. He completed his active duty commitment in 2010.
