The Pentagon released the identities Monday of the two soldiers killed in action late last week in an Iranian ballistic missile and drone attack in Jordan.

U.S. Army Pvt. Isabella Gonzales, 19, of Carrollton, Texas, and 1st Lt. Tyler James Feehan, 25, from Ewa Beach, Hawaii, died July 17 and July 18, respectively, according to a Department of Defense release.

The active-duty soldiers were killed during an enemy attack at Muwaffaq Salti Air Base, Jordan.

Gonzales was stationed at Ansbach, Germany, assigned to 1st Battalion, 57th Air Defense Artillery Regiment, 52nd Air Defense Artillery Brigade, 10th Army Air Missile Defense Command.

Feehan was stationed at Fort Bragg, North Carolina, assigned to the 2nd Battalion, 55th Air Defense Artillery Regiment, 32nd Army Air Missile Defense Command.

The incident is currently under investigation, the release states.

On Saturday, U.S. Central Command announced that another U.S. service member is missing following the attack, while four troops, who have since been discharged, were medically evacuated to hospitals in Jordan.

For the ninth consecutive night, the U.S. “hit [Iran] very hard again tonight,” President Donald Trump said on Sunday. The strikes, he said, were in honor of the soldiers who were killed.

“The strikes will continue degrading Iranian military capabilities used to attack commercial vessels and civilian mariners transiting the Strait of Hormuz,” a CENTCOM post from Sunday reads.

Trump said that “probably” three service members were killed in action, as opposed to two.

As of Monday morning, the Pentagon had not clarified whether a third service member was killed in action.

The command said in a social media post Sunday that U.S. military personnel found unidentified remains at the location of the attack. CENTCOM said that an examination process to verify the remains is ongoing.

The deaths of Gonzales and Feehan bring the toll of American troops killed in the war with Iran to 16. More than 400 U.S. troops have been wounded in the campaign, which began Feb. 28.

Separately, on July 18, a U.S. service member was killed in action in northern Iraq during a controlled detonation of unexploded ordnance from a downed Iranian one-way attack drone.

“A second service member was wounded and continues to receive medical treatment for a minor injury,” CENTCOM said in a statement.

CENTCOM had not yet provided additional information Monday, such as the identities of those service members killed or missing.
