I put "realistic", but it's really not quite accurate. I, like many others, like my Joe vehicles to be pretty grounded in reality, but Cobra I can definitely see branching off into the more fantastic designs. The HISS tanks, the MAGGOT (looking past seperating the components), the MAMBA are all awesome examples of the "acceptable", yet unrealistic, vehicles. Cobra is unconventional and a lot of their power comes from being terrorists; their image is important because fear is their greatest weapon and I think that shows in their uniforms, armor, weapons and vehicles. The ROCC and the RHINO, however, on the Joe side of things, are definitely futuristic, but I wouldn't say they were unrealistic (think science-fiction here).
