The T-600 is humanoid in appearance, functioning primarily as either a soldier or an assassin in various situations. In addition, some T-600 units are covered in a sheet of rubber skin, meant to resemble that of a human. These units are typically used by Skynet for espionage and infiltration purposes rather than direct combat. However, the T-600's importance in these roles may have diminished due to the development of more advanced terminator models such as the aforementioned T-800 and the T-1000.
