The Pentagon on Friday identified the three U.S. Army Green Berets who were killed this week during what it described as an advise-and-assist mission in Niger.

The soldiers were Staff Sgts. Bryan C. Black, 35, of Puyallup, Wash.; Jeremiah W. Johnson, 39, of Springboro, Ohio; and Dustin M. Wright, 29, of Lyons, Ga., according to the announcement. All three were assigned to the 3rd Special Forces Group based at Fort Bragg, N.C.
