BALAD AIR BASE, Iraq -- Senior Airman Othelia Richards observes a third-country national truck convoy delivering concrete mix here. Third country nationals and local nationals make up a large percentage of the workforce for construction projects and day-to-day jobs around the base. An escort's job is to monitor workers and provide security. For many escorts, the job requires long days in the scorching sun with weapon in hand and a careful eye watching for suspicious activities. Airman Richards is assigned to the 332nd Expeditionary Civil Engineer Squadron. (U.S. Air Force photo by Staff Sgt. Chad Chisholm)
