Cobra Rock Vipers are mountain assault specialists trained in mountaineering and vertical assault. They are experts at climbing treacherous terrain of rock, snow or ice. They use sophisticated climbing gear and weapons designed for compactness and versatility.


The two releases were nearly identical in every way. The only differences are the shade of red paint is slightly different (only noticeable when compared side-by-side) and the forearms use different colors of plastic. The Pursuit Of Cobra release has flesh colored plastic with the arm guards painted red. The 50th Anniversary release had red colored plastic with flesh painted on.

The display stand for the 50th Anniversary release was black and gold.
