The Pentagon on Wednesday identified the three U.S. service members killed by a roadside bomb earlier this week in central Afghanistan. U.S. Army Green Berets Captain Andrew P. Ross, Sergeant 1st Class Eric M. Emond, and U.S. Air Force Staff Sergeant Dylan Elchin all died from the attack that occurred Tuesday near the Afghan city of Ghazni in what was the deadliest day for U.S. troops there this year. Taliban militants reportedly claimed responsibility for the blast. Three other U.S. soldiers were also reportedly wounded in the attack and are said to be in critical condition, according to a source cited by Newsweek. An American contractor who was also injured in the blast has reportedly died. The Pentagon has not yet officially confirmed the conditions of those wounded. Ross, who hailed from Lexington, Virginia, had reportedly served more than seven years in the U.S. Army and was on his second tour when he died. Emond, from Washington state, served for more than 21 years and was reportedly on his “seventh and final overseas deployment. Newsweek reports Elchin had just completed Airman Leadership School in October 2017 before he was killed.
