In the TV show the "The Punisher" (s01e07) there is a scene where Frank Castle attempts to kill a man standing at a window using a sniper rifle:

To his surprise the glass stops the .338 sniper shot. Based on a quick Google search it would take 3" of polycarbonate to stop that and 1' of tempered glass. The window in question definitely wasn't that thick, so I'm wondering: is there a material of which an inch or less could stop a sniper round or was that complete fiction?

    The show is set in the MCU, a world of make-believe meta-materials with incredible properties.

    Bullet proof glass is generally a compound material made from multiple layers of different substances laminated together, so it's much stronger than thick sheet of a single Material. Aug 4, 2023 at 15:58

    That is the entire point of bullet-proof glass...

    @ethan - It's on-topic and answerable in the context of the TV show

In the real world, no. As you've said, any bulletproof glass strong enough to resist a sniper's bullet ("Level 10") would have to be at least a couple of inches thick unless the round was fired from especially far away.

That being said, we've seen other instances of extremely thin bulletproof glass being used elsewhere in the Marvel Cinematic Universe.

This is a world where levitating cars have been a reality since the 1940s and the public have access to meta-materials that are stronger and lighter than their real-world counterparts.

  • And yet real cars can have windows withstanding sniper rounds. It's not so simple to tell how thick glass is - one could have serious trouble telling that windows in such car are so thick.
