AR RAMADI, Iraq (March 12, 2005) - Rex, a three-year-old Belgium Malonois, does a thorough inspection of the trunk of a vehicle, which belongs to an Iraqi who was selected for a random inspection at a vehicle checkpoint here. Sergeant Christopher L. Olinger, Air Force Tech Sgt. Robert P. Hansen and Lance Cpl. Marshall S. Spring, military dog handlers with Operation Force Protection, I Marine Expeditionary Force, and their canines, Jack, Nero and Rex can be seen searching vehicles at the three vehicle check points just outside the Hurricane Point camp's perimeter. The six are here supporting Operation Iraqi Freedom while attached to 1st Battalion, 5th Marine Regiment. They each do between 40 and 50 random searches a day in an effort to detect and stop improvised explosive devices and vehicle born IEDs from being delivered and doing harm. They are the Marine Corps' first line of defense against insurgents bringing explosives and materials to make explosives into the southern part of the city.
