Aug. 17 (UPI) -- A member of the Utah National Guard was killed during a military operation in Afghanistan, the U.S. military said Thursday.
The slain soldier was identified as Aaron Butler, 27, his family confirmed to KSL-TV, Salt Lake City.
"The Army values are loyalty, duty, respect, selfless service, honor, integrity, personal courage," the Butler family said in a prepared statement. "Aaron Butler personified those values in everything he said and did. In a life that was all too brief, our dear son and brother made the ultimate sacrifice for his country."
The family added: "While we are heartbroken to become a gold star family, we honor Aaron's service and sacrifice. Aaron was a strength to us, an inspiration to those around him, and a joy to have in our family."
