Something tells me this dio will never come to be.... Again, like everyone has said, do your research!
Come on, 3 + armored vehicles, each taking at least 50 hours to build, plus 25 soldiers about? and a highly complex bridge in 1/35.... Let's think this through, how about a 1/72 dio? costing about $90 total. Now, let's say that same dio in 1/35.... 3 armor kits $100, a crapload of styrene stock $30, figures $40, paint $30. $200 there and that's not including supplies, accessories, diorama bases, time, etc. So, basically over $300 worth of something that may be innacurate, not make sense, and poorly planned.
I'm seriously not trying to discourage you at all. Just, like I said before, trying to open your eyes.
Also, this is the third or fourth dio ideas you've posted here that are on this immense size with the same amount of thought put into each one. If you can't keep one idea at a time, how can you expect to invest MANY hours in one area?
Also, this site is one of the best resources ever for this kind of research.
I'm sorry if I came off as mean, but, this is my opinion...
Tankluver, have you checked your E-mail lately?

No wait, that's not it.
