The Pentagon on Wednesday identified the remaining two of the six American troops killed in the opening hours of the war with Iran.

Maj. Jeffrey R. O’Brien, 45, of Indianola, Iowa, and Chief Warrant Officer 3 Robert Marzan, 54, of Sacramento, California, were killed Saturday in Kuwait from an Iranian drone attack, the Pentagon said. Marzan is "believed to be the individual who perished at the scene," the Pentagon said, and positive identification will be completed by a medical examiner.

Our Soldiers relentlessly, consistently, and fearlessly served with sincere dedication and pride," said Brig. Gen. Clint Barnes, Deputy Commanding General, 1st Theater Sustainment Command, Operational Command Post. "They were the ultimate ambassadors for freedom."

The joint U.S.-Israel campaign entered its fourth day Tuesday, with American forces having struck more than 1,700 targets inside Iran as fighting spread across at least a dozen countries.

Trump and top Pentagon officials warned the toll is expected to rise.

"We expect to take additional losses, and as always, we will work to minimize U.S. losses," Gen. Dan Caine, chairman of the Joint Chiefs of Staff, said Monday.
