>You're gonna do what, hold your backpack out at arms length and hope they don't shoot you anywhere else?
So I guess soldiers, law enforcement, firearm instructiors, armed security officers, and all them just stop wearing body armor, since they'll just get shot somewhere else.
>And hope that they're not using a rifle that will just blow through it anyways?
Level 3 or 3+ will stop most 5.56 (including M855, depending on the plate composition) or ball 308 just fine, and even against 308 AP rounds it could turn a fatal hit into one that is merely dangerous. It also is amusing that you dollow up this comment with pushing OP towards soft armor that would do jack shit against any 5.56 or 308.
