Jose Regalado, 23
Regalado was one of two soldiers killed in Mosul, Iraq, when an Iraqi Army soldier wearing a uniform approached the men and opened fire. He had carried his daughter’s ultrasound throughout his deployment as a good luck charm. After Jaimie was born, his wife sometimes wore his cologne so that the infant would recognize her father when they finally met.
