I can't figure out why people are being so dense about it. The sheets used for the door on the production vehicles are 14ga (1.8mm thick) 301 stainless steel. Some of the original prototypes used 3mm thick, which would approach some level of effectiveness against handgun ammo. But because that just makes the whole truck heavy as fuck for no reason, they did the obvious thing, which was to just use thinner, non-bullet-proof steel.
