In the seventy-fifth year of the Pendulum Wars, Packhorses were used by C Company of the 26th Royal Tyran infantry to patrol the Acastu Imulsion Fields. When an Indie special forces unit attacked the fields, Sgt. Bernadette Mataki drove a Packhorse to reinforce a Gear squad fighting them, with Sgt. Daniel Kennen manning the gun. Kennen cut down several Indies, and after the UIR forces retreated, Cpl. Maxon, who had been shot in the throat, was loaded into the Packhorse and taken to a medical facility. A week later, Pvt. Carlos Santiago drove a Packhorse during a patrol around the base with Pvt. Marcus Fenix and Pvt. Quinn.
