On Oct. 18, 2006, Justin Constantine was deployed to Al-Anbar Province, Iraq when a sniper shot him in the head.
He had just stepped out of his Humvee to warn a reporter about the sharpshooter operating in the area when the enemy took the shot.
"He [the reporter] told me later that based on that [Constantine's warning] he took a big step forward and a split second later a bullet came in right where his head had been and hit the wall between us," Constantine, who retired a Marine lieutenant colonel, said in the video below. "Before I could react, the next bullet hit me behind the left ear and exploded out of my mouth, causing incredible damage along the way."
Constantine's original prognosis was "killed in action," but thanks to a quick-thinking 25-year-old Navy Corpsman, he lived.
"Even though blood was pouring out of my skull in what was left of my face, George was somehow able to perform rescue breathing on me, and then he cut open my throat and performed an emergency tracheotomy so that I wouldn't drown in my own blood," he added.
The Corpsman's first aid was so perfect that Constantine's plastic surgeon at the Naval Hospital thought another surgeon had performed the procedure.
He retired from the Marine Corps with a Purple Heart Medal, Combat Action Ribbon and Navy-Marine Corps Commendation Medal for his service in Iraq.
Despite his recovery challenges and PTSD, Constantine has led an inspiring post-injury life, helping veterans and civilians overcome adversity. He now serves on the Board of Directors of the Wounded Warrior Project, Give An Hour, and others.
He now shares his wisdom and life-saving resiliency lessons he learned in the Corps with all Americans via his "Veteran Calendar" and uses a portion of the proceeds to support the Semper Fi Fund, The Medal of Honor Foundation, and The PenFed Foundation.
