The 1982 Cobra Trooper v1, The Enemy, came with a red Cobra chest logo, which can be easily scratched or rubbed off. The silver parts of his uniform may also be rubbed off or scratched.
V1 Cobra Officer was available as both a carded figure and packaged with the 1982 Sears Cobra Missile Command Headquarters along with v1 Cobra Commander and v1 Cobra Officer.
While this figure's filecard clearly reads COBRA, and not Cobra Trooper, it is frequently referred to as a Cobra Trooper to disambiguate it from Cobra the organization and its other members. For example, just in 1982, Cobra (trooper), Cobra Officer, and Cobra Commander are all part of Cobra. If one refers to a 1982 Cobra, they are most likely talking about the trooper, but technically all 3 of those figures are 1982 and Cobra. The trooper addendum more than likely came about from these characters being called as such many times in the popular A Real American Hero cartoon series produced by Sunbow.
