I dont understand why you had to model each tank by hand... You could've just model one of them, UV it and then clone away
For a multitude of reasons:
a) I like every sub-object (in this case, the tanks) to be one single poly/element. If that mesh is unified and simple (there is a proper word for this...manifold? I think), it eliminates all kind of collision errors. The alternative would be to make each tank a sub-object, but that would be ridiculous-we're talking 70+ tanks here...
b) There will be different strips of metal, girders and so on overlaying the tanks (textured). If I used a single UV template for all the tanks, they'd come out exactly the same. Do not want.
c)Final 'tank' subobject: see below. That's a
single mesh and element.
I admire your dedication. The results are brilliant. 
But why aren't you doing the teeth again?
Thank you. Again, for a multitude of reasons, the main ones being that a) if I did, I'd have to re-UV the bow and change the normal maps (

) and b)I kind o' like it this way...
