The Utah National Guard has identified the service member as Mayor of North Ogden, Brent Taylor, North Ogden City Councilman Phil Swanson confirmed on Saturday.
U.S. Sen. Orrin Hatch, R-Utah, in a Twitter message, described Taylor's death as "devastating" news.
Residents of North Ogden, a community of about 18,000 people, north of Salt Lake City, remembered Taylor as a leader and mayor willing to listen. This war has once again cost us the best blood of a generation. "The entire Herbert family mourns with this soldier's family and we pray that their burdens may be lifted, and that the hearts of all Utahns will reach out to comfort them in their grief".
The city of North Ogden is planning a memorial for Taylor, but details of the event have not been released yet.
Taylor was a longtime member of the Utah National Guard, and in January, he was deployed to Afghanistan.
Taylor was part of an advisory team tasked with training Afghan commandos.
The two United States service members were medically evacuated to Bagram Airfield and the wounded service member was undergoing medical treatment and is in stable condition.
"These reports also indicate the attacker was immediately killed by other Afghan Forces", the statement said. Indeed, Burton underscored the fact that other Afghan forces killed the suspect who had fired on Taylor with "small arms fire".
Taylor is survived by his wife, Jennie, and seven children, according to the Tribune.
"For me personally, Brent typified the citizen soldier".
Taylor served two tours in Iraq and was on his second tour in Afghanistan.
His last Facebook post, on October 28, highlighted a successful election in Afghanistan.
Taylor was a Ph.D. candidate at the University of Utah in worldwide relations after receiving a Bachelor of Arts at Brigham Young in political science and a Master of Public Administration from the Unifersity of Utah. But months away from his return, Taylor was killed during an apparent insider attack Saturday in Kabul.
Taylor, who joined the service in 2003, had insurance, Burton said, and will also receive the aid of a "casualty assistance officer".
An online GoFundMe campaign for the Taylor family had generated more than $160,000 in donations as of Sunday afternoon and the number continued to climb.
