Police officers of the Noblesville, Ind., Police Department's Emergency Response Unit "stack up," moving as one autonomous unit, scanning their respective sectors while breaching and clearing the Camp Atterbury Joint Maneuver Training Center's Live Fire Shoot House in central Indiana, May 13. The officers are a part of what is essentially a SWAT team with added responsibilities. The training facility gives military and law enforcement personnel the opportunity to use live ammunition in close quarters situations. Its wall's are covered in a form of rubber that absorbs ricochets, protecting operators from injury.
