You'll probably have a very difficult time finding any military hardware that isn't in 1/35, and if you ask someone to print military hardware that isn't in 1/35, they'll probably just say "No" (after laughing hysterically). That being said, you could try mikeegoldberg over on Cults3D. He has a lot more than what is shown as I don't think he's transferred his entire catalog over from Shapeways yet.
Good luck.
