Truck 4 was part of a four unit convoy of transport trucks transporting Confederate marines from Boro Airbase on Turaxis II during the Guild Wars. Unlike the other trucks, it was loaded with equipment. When the convoy came under attack by Kel-Morian Hellhounds, Truck 4 was the only one that escaped unscathed. It was then driven by Private Jim Raynor, pushing the wrecks of trucks 1 and 2 off the road. Along with a newly repaired Truck 3, it set off for Firebase Zulu.
