One had a 2-year-old son and a 2-month-old daughter. Another had been a star linebacker on his high school football team. Another had planned to pursue a career in medicine but enlisted in the military after being captivated by the idea of going on special operations.

The Pentagon has not publicly identified the 30 American troops who were killed over the weekend when their helicopter went down in eastern Afghanistan. But in cases in which the families have been notified, relatives and friends have begun to talk about the fallen in interviews with local media outlets and others.

In describing their loved ones, they paint a portrait of a diverse group of service members committed to their jobs and to their country.

Below are links to stories about some of them. Ranks will be added pending identification by the Pentagon.

The full list of casualties will be posted when it is available.
