While many Cobra soldiers might not be able to share the skill level of one G.I. Joe specialist, many of them make up for their deficiency by incorporating some form of stealth technology to supplement their function in the battlefield. The H.E.A.T. Viper is one such Cobra. His rocket launcher is incorporated with heat suppression technology which allows him to escape infrared detection. His helmet is linked to a sophisticated targeting system that essentially takes care of locking on to the target, estimating range and trajectory and image intensification.
