The Department of War has identified the remaining two American service members killed in an Iranian drone strike in Kuwait on March 1, completing the release of the names of all six troops who died in the deadly retaliatory attack. 

The War Department identified Maj. Jeffrey R. O’Brien, 45, as one of the casualties, and believed Chief Warrant Officer 3 Robert Marzan, 54, to be the other casualty, but a medical examiner will need to confirm his identity.
