The ALLEY VIPERS are the Cobra equivalent of a police S.W.A.T unit or a British S.A.S. They form the spearhead of Cobra's inner-city invasion forces. This elite contingent of marauders are true masters of brutality, possessing a style of ruthlessness not present in other Cobra soldiers. Recruited from Cobra's most diabolical combat divisions, Alley Vipers use various forms of treachery to achive their objectives. In order to graduate from their traning program, they are required to survive a full burst of machine gun fire their frontal body armor, execute a thirty foot jump onto concrete with full combat armor and run down a hundred meter, gas-filled corridor without a gas mask.
