Two U.S. military personnel were killed and one went missing when Iran launched ballistic missiles and drone attacks against a U.S. base in Jordan on Friday, marking the first American combat deaths from direct Iranian fire since the ongoing conflict began in late February 2026. This is the first time U.S. troops have been killed in direct Iranian military operations during the current war. The incident triggered swift U.S. retaliation — the military launched airstrikes against Iran's Revolutionary Guard on Sunday, expanding the scope of the conflict beyond previous exchanges.
