Same thing. It has to be barely thick enough to stop a predefined caliber weapon. And made of the cheapest possible material that still makes the armored vehicle mobile. Equipping armies is kind of expensive.

It generally means the cheapest option with the simplest possible operation that does the job well enough.

I don’t think so. My kid likes the stories though :)

I use it to have it write stories of our cats and an imaginary cat having adventures with a princess for my kindergarten kid. It’s really good at it :)
