HISS Tank (Found in 2 pieces, with neither of the guns)
Air Defense Unit
Quick-Steel Epoxy
Man-O-War labels
I got the idea to make this one a while back, but didn't want to destroy a perfectly good HISS tank (Septic Tank maybe, but that's another story). Fortunately I found one suitable for customizing, and some dremmeling, Epoxy and paint applications later, it was ready. Plus the missile system is only on the turrent, so I can switch it to another HISS tank with that turrent setup.
Cobra SMS Prototype
AKA Missile HISS
Originally, the SMS was intended to be a HISS refitted with twin surface-to-air missile launchers. MARS constructed a prototype, and several dozen where produced, however due to its awkward shape Cobra Commander halted production in favor of the simpler, and less expensive, "Crimson HISS". The few Missile HISSes that where constructed where used as Anti-Aircraft sentrys around Cobra Island Airfeilds.
