For 11 consecutive days, the U.S. has conducted major air strikes against Iran, while Iran has carried out drone and ballistic missile attacks on U.S. forces and allied targets across the region. The rapid return to war follows the collapse of a shaky cease-fire between the two countries. And though negotiations appear to be continuing at least in some form, there does not seem to have been any progress back toward peace. On Tuesday, Donald Trump vowed to bomb Iran’s underground military facility at Pickaxe Mountain, where Israel reportedly told the U.S. Iran had moved some of its nuclear centrifuges. The war may pause again, but it appears unlikely to happen anytime soon. Below, a look at all the costs of a resurgent conflict.

. 4 U.S. service members have been killed and nearly 100 injured during the new phase of the war

On Friday, three U.S. Army soldiers were killed during an Iranian ballistic missile attacks on a U.S. base in Jordan, 1st Lt. Tyler James Feehan, 25; Pvt. Isabella Gonzales, 19; and Sgt. Angel S. Rampersad, 28, who is still missing but presumed dead. On Sunday in Iraq, a 30-year old U.S. Army soldier, Sgt. Michael Emmanuel Swinton, was killed after being struck by debris during the controlled demolition of a downed Iranian drone. That raises the total number of U.S. service members killed during the war to at least 18. Trump has vowed revenge against Iran over the latest casualties and is reiterating that the soldiers died for something important:

According to the Pentagon, almost 100 service members have been injured in Iranian attacks since July 7. The Pentagon classifies most of those injuries as minor.

Iran says that at least 50 people have been killed in U.S. air strikes over the past three weeks and that more than 500 people have been injured.

. We rarely know how much harm and damage Iran’s attacks are doing

Throughout the war, the Trump administration and the Pentagon have not disclosed the full picture of damage and casualties from Iranian attacks, citing operational security. This new phase has been no different. The New York Times reported Monday that Iran attacked U.S. forces three times last week, injuring dozens of service members, and that the Pentagon had not acknowledged it. Later Monday, the Pentagon announced updated, higher casualty figures while criticizing coverage suggesting it was hiding anything.

. Iran may have shifted tactics, increasing the risk to American soldiers

The Wall Street Journal reports that Iran may have targeted U.S. service members’ living quarters at Muwaffaq Salti Air Base in Jordan in attacks that killed at least two Americans last week:

While Iran has made repeated efforts with missiles and drones to hit the crowded base, no evidence has been released by U.S. officials that shows Iran specifically targeted the servicemembers’ quarters, known as “containerized housing units” or CHUs, in an effort to cause widespread casualties.During the first of the three missile attacks on Muwaffaq Salti Air Base, debris from the missile strike hit the base’s gym, U.S. officials said. A siren signaling the incoming attack sounded in time for troops to try to shelter in the bunkers. Some were wounded on the way to the bunker, but none were killed, officials said. Hours later sirens sounded again, sending troops heading toward the bunkers. This time, an Iranian missile hit an empty aircraft hangar, officials said. The third missile strike hit containerized housing units, where soldiers had been sleeping, the officials said. The sirens sounded for a third time, but not everyone made it to the bunkers.

CBS News spoke with a Jordanian military analyst who pointed out that Iran wasn’t just getting lucky but was effectively evading U.S. and allied air defenses:

“The Iranians have advanced missile technology,” said Jordanian Lt. Gen. Qasid Mahmoud, who served as Deputy Chief of Staff for his country’s armed forces before he retired. “They’re developing techniques and capacities to extend their reach, combining with drones to overwhelm radar defenses.”“The Iranians use simple missiles to distract the radar,” Mahmoud, who has studied Iran’s military capabilities for years, told CBS News. “They........
