I always think its funny how bullets never seem to penetrate anything in movies. Like, guy hiding behind a barrel? Nope, cant penetrate, even with a rifle. The newest Batman movie had me shaking my head as he shrugged off multiple rifle rounds to his armor.

Bullets are insanely dangerous and powerful. A .223 round can penetrate a solid brick wall pretty easily, and can destroy a cinderblock wall with some effort. Even if it doesnt penetrate, the amount of force applied is incredible. Plates designed to stop bullets have to be made in specific ways to make sure a bullet doesn't penetrate, but even with that plate, the sheer force of an impact can break bones.
