Most of the casualties, 271, were U.S. Army servicemembers while the others were U.S Navy, U.S. Air Force or U.S. Marine Corps personnel, Defense Casualty Analysis System (DCAS) data on Operation Epic Fury revealed. The Navy suffered 64 wounded, the Air Force 46 and the Marines 19. All were listed as due to hostile action.

President Donald Trump announced a halt on military action for two weeks April 7 on Truth Social, calling it a “double-sided ceasefire.” The president’s announcement came hours after he said a “whole civilization will die” ahead of a deadline at 8 p.m. that day.

Following the breaking down of negotiations in Pakistan, Trump ordered a blockade of Iran on April 12, later extending it and the ceasefire on April 21.
