Mr brother (of all people) found this website, and I thought all you might want to check it out. It's got line drawings, or 'blueprints', of lots of AFVs. There's also some pretty cool 3D renderings of non-armor stuff. Check it out: http://www.suurland.com/
To get to the armor drawings, click on 'blueprints' on the left side of the screen. Then, pick your category. They've got planes and ships too. Enjoy!
