Check out the Sgt. Slaughter & his Triple T commercial:
http://www.youtube.com/watch?v=EUbgVzMboKs&NR=1Note 2 things, 1) in the animation Cobra is using the Thunder Machine as a standard "army built" vehicle. 2) Sgt. Slaughter and at least the BAT appear to be prototypes.
Now compare it to this UK version. It's the 2nd of 4 in this video:
http://www.youtube.com/watch?v=tU5Z857d ... re=relatedSame basic commercial, but it's totally redone. No obvious prototypes used this time around. But check out the animation. It's completely redrawn, and much simpler. This time around the Cobra BATs are mostly in Viper colors. Can't imagine what was wrong with the first animation that they felt they needed to redo it? Wonder how often other International commercials that seem to be identical at a glance are actually re shot?
While your at it, take a look at the last group shot of figures in the Zanzibar commercial. That last Zanzibar appears to have a T-crotch, while the single figure just a few moments earlier is perfectly normal. The group shot also show's prototype BATS that look much earlier than the ones in the Slaughter commercial, and what appears to be a prototype Viper with a completely different chest.
