Soldier Killed in Afghanistan Blast Was Army Green Beret

Staff Sgt. Matthew V. Thompson was killed by a roadside bomb Tuesday.

— -- An American soldier killed by a roadside bomb Tuesday in Afghanistan's Helmand Province has been identified as Staff Sgt. Matthew V. Thompson, 28, of Irvine, California.

Thompson was killed by a bomb blast that left another American service member injured and six Afghan soldiers.

In a statement, General Joseph Votel, commander of U.S. Central Command, expressed his condolences to Thompson's family.

"On behalf of the men and women of U.S. Central Command, I extend our sincere condolences to the family, friends and Sgt. Thompson's fellow service members, as well as gratitude for his selfless and honorable service to our Nation."

Thompson is the second U.S. combat death in Afghanistan this year. In January, fellow Army Green Beret Staff Sgt. Matthew McClintock, 30, died after an hours-long firefight near Marjah, also in Helmand province. He was assisting Afghan special operations troops as they defended against an intense Taliban assault.

A U.S. official said that Thompson was not one of the 100 U.S. troops recently sent to Lashkar Gah to train, advise and assist local Afghan police as they face a major summer offensive by the Taliban. That group includes trainers as well as a force to provide protection for them.
