SAN ANTONIO -- Airmen take part in a truck convoy during a basic combat convoy course on-road training scenario. The course is designed to train transportation Airmen in basic combat skills required to integrate with joint forces in hostile convoy operations. Airmen receive about 300 hours of training at nearby Camp Bullis to prepare them for security escort and line haul missions with coalition convoys supporting Operation Iraqi Freedom.
