The Skynet Express was a Non-Humanoid Hunter Killer in operation during 2018. It was tasked with transporting various minerals via rail car, to Skynet outposts in the Alaska territories. Because of its importance, the Skynet Express was under constant guard by a minimum of one Aerial Hunter Killer, a swarm of Aerostats, a platoon of T-600s, and specialized Moto-Terminators known as Snowminators.
Due to its importance, the Alaskan Resistance launched an attack on the Skynet Express in order to capture the minerals it was transporting and to destroy the remainder of its cargo. The Skynet Express was destroyed in the process; however, the Resistance squad assigned to the attack took heavy casualties.
