According to the Department of Defense, an Oklahoma national Guardsman was killed in a rocket attack in Iraq. 

Staff Sergeant Marshal D. Roberts, 28, was killed Wednesday while deployed in support of Operation Inherent Resolve. 

Roberts was a member of the 219th Engineering Installation Squadron, 138th Fighter Wing, headquartered in Tulsa. He also served as the 219th senior personnel noncommissioned officer while deployed, officials said.

"Oklahomans all across the state mourn the loss of Staff Sgt. Roberts,” said Kevin Stitt, Governor of Oklahoma and commander in chief of the Oklahoma National Guard. “Today serves as a reminder of the many brave men and women who put their lives on the line every day to defend our state and country. Our prayers are with Staff Sgt. Roberts’ friends and family during this time, and the state is prepared to offer any support possible.”

“We are devastated by the loss of Staff Sgt. Roberts who served selflessly and with honor,” said Maj. Gen. Michael Thompson, adjutant general for Oklahoma. “I ask that every Oklahoman pray for the family of this fallen patriot and keep them in your thoughts in the days and weeks ahead.

“Our casualty assistance team is working with the family to help them through this terrible time,” Thompson added. “We also have teams available for service members in need of assistance.”

"With the passing of Staff Sgt. Roberts, the 138th family has lost a dedicated Airman, mentor and leader," said Col. Michael Meason, commander of the 138th Fighter Wing. "Our thoughts and prayers are with Staff Sgt. Roberts' family and friends as we stand with them through this difficult time. They are and always will be part of the 138th family."

Department of Defense officials said Roberts is the first Oklahoma Air National Guardsman killed in action. He is the 20th Oklahoma National Guardsman to die while deployed overseas since 2001.
