As the first generation of human-mimicking Infiltrators deployed by Skynet against the Resistance, the T-600s displayed all of the problems that come from rushing a prototype into production. Covered in unconvincing rubber skin and lacking any organic components, they were easily detected and destroyed. But if there's one thing that Skynet is good at, it's learning from its mistakes.
