Bio: Cobra's standard rocket soldier is the High-Explosive Anti-Tank Viper, the H.E.A.T.-Viper. Risen from the ranks of the Vipers and trained in propelled explosives, the H.E.A.T.-Viper is the stepping stone for those who wish to be Flak Vipers or the fearless Fast Blast Vipers. Over the years the H.E.A.T.-Viper uniform has changed, from the original yellow and purple with its distinctive half armored/half visor helment to the green uniform with helment covering only the upper part of the face, to the current red and black uniform shown here. One of the few alliances within the ranks of Cobra is that of the H.E.A.T.-, Flak, and Fast Blast Vipers and the Laser Viper corps, who provide target illumination for their rockets to home in on.

"A H.E.A.T.-Viper is a tank driver's worst enemy, because they're trained to take out tanks. Of course, they try to get a first-round kill, there's no G.I. Joe alive who would let them last long enough to get off a second." -- Second Lieutenant Ralph Pulaski, "Steeler"
