President Barack Obama is going the present the Medal of Honor to a Marine who took on enemy fire in Afghanistan to find and bring back three missing Marines and a Navy corpsman. Dakota Meyer, who left active duty in June 2010, will be the first living Marine in 41 years to receive the nation’s highest award for valor. Only two living recipients – Army Staff Sgt. Salvatore Giunta and Army Sgt. 1st Class Leroy Petry – have received the award for actions in Iraq and Afghanistan.
