A Navy cryptologic technician based at Fort Meade was among the four Americans killed in a suicide bomb attack claimed by the Islamic State group in Syria this week, the Pentagon said.

Officials identified her as Chief Shannon M. Kent, 35, from upstate New York.

“She was a rock star, an outstanding Chief Petty Officer, and leader to many in the Navy Information Warfare Community,” said Cmdr. Joseph Harrison with the Commanding Officer of Cryptologic Warfare Activity 66, where Kent was assigned after the command was established in August.

Also killed in the attack were Army Chief Warrant Officer 2 Jonathan R. Farmer, 37, of Boynton Beach, Fla., who was based at Fort Campbell, Ky., and a civilian, Scott A. Wirtz, from St. Louis, Mo. The Pentagon has not yet identified the fourth casualty, a civilian.
