HARRISBURG — Military officials say a member of the Pennsylvania National Guard is dead after being severely wounded by small-arms fire in Iraq.

Staff Sgt. Mark Baum was killed Saturday after his quick-reaction unit responded to an improvised explosive device attack in Mushada. He was airlifted to Baghdad and died five hours later.

The 32-year-old Baum was from Quakertown and was assigned to the 56th Stryker Brigade Combat Team.
