The Spider Tank is one of Skynet's Non-Humanoid Hunter Killers as a principal ground-based combat robot. Spider Tanks are roughly two-and-a-half times the height of a human being. They are quadrapedal ground units of a similar design to the HK-Centurion. Spider Tanks have two arms, each with a forward-facing and rear-facing plasma cannon. A Spider Tank is stored in the belly of an HK-Aerial for transportation.
