The Defense Department on Monday identified the Navy SEAL killed during a raid on al Qaeda militants as Chief Petty Officer William "Ryan" Owens.
In a statement, Defense Secretary James Mattis said Owens, 36, "gave his full measure for our nation, and in performing his duty, he upheld the noblest standard of military service."
Owens was killed in a firefight during an intelligence gathering raid that left three more SEALs wounded.
Two other SEALs were injured when their aircraft, an MV-22 Osprey, experienced what Pentagon officials described as a "hard landing."
