The trouble with armored vehicles is that at some point you have to see out of them, and that requires glass, and glass doesn't resist ordnance all that well unless you use so much of it that you can barely see through it.
Now there's a layered aluminum oxynitride armor, backed up by a polymer with just a little glass in the middle. It's nicely clear, and in testing this summer it stopped a .50-caliber round. Try that with glass.
Right now, the stuff is about twice as expensive as glass, but you have to figure it's going to last quite a bit longer.
