On March 3, President Donald Trump and many senior officials warned that the conflict with Iran would cause more US soldiers to die as Tehran responded to US and Israeli airstrikes.
The US Central Command said Iran has launched more than 500 ballistic missiles and more than 2,000 unmanned aerial vehicles in retaliatory rounds across the Middle East.
The risk to US forces in the region was mentioned in a closed-door meeting with parliamentarians chaired by Secretary of War Pete Hegseth, Chairman of the Joint Chiefs of Staff Dan Caine, CIA Director John Ratcliffe and Secretary of State Marco Rubio. Senator Chris Murphy said officials announced that more Americans would be killed and they could not completely prevent drones.

The US military has also confirmed the identities of 4 of the first soldiers killed in the war with Iran, amid President Donald Trump's administration warning that increased conflict would cause further losses to US forces.
Among the 6 US military personnel who have died so far, 4 belong to a US Army Reserve unit in Iowa. They died on March 1 when a drone crashed into a US military facility in Shuaiba port, Kuwait, according to the military's announcement.
The Pentagon said 4 military personnel aged 20 to 42, serving in Logistics Command 103 in Des Moines, Iowa, belong to the US Army's global logistics and supply system.
The announced identities include: Captain Cody A. Khork, 35 years old, from Winter Haven, Florida; Sergeant Noah L. Tietjens, 42 years old, from Bellevue, Nebraska; Sergeant Nicole M. Amor, 39 years old, from White Bear Lake, Minnesota; Sergeant Declan J. Coady, 20 years old, from West Des Moines, Iowa.
Major General Todd Erskine, Commander of the 79th Battlefield Logistics Command, expressed "deep sympathy and respect" for the relatives and members of the unit of the 4 soldiers.
