No. A direct hit from a tank gun okay yeah it's a miracle if the victim survived but small arms it's a matter of the degree of hit and where hit.
Mammals have traded off some survivability vs our reptilian ancestors but still a human body is not easy to kill.
AP rounds trade off terminal ballistics vs penitration.
The method of kill for a AP that has penetrated is primarily to induce significant blood loss. But blood loss takes time and can be countered. The only absolute instant kill is to take out the brain stem that is absolutely lethal. But that's a hard to make shot.

Really?? Didn't the PLA just clone Multicam?
And metamaterials are the dream of all armies but doesn't seem practical.
Yeah that was a stupid typo. Only the heavier weapons would outright kill you. But in a modern conflict you would still be very fucked if you were hit by a rifle. You’ll be pinned in place, need a squad mate to carry you out, while making you a huge target for stuff that could kill you immediately.
Point is, armor would only weigh you down, and in worst case make sure the bullet stays inside your body instead of overpenetrating.
What is wrong with multi cam? Thought US and Russia both used it as well?
Metamaterial seems to be a project in the works. It might not practical right now, but 10 years down the line it could be. It looks like the first wave will be used on vechicles to mask signature.
Edit: regarding your 2nd post, stuff like quantum radar, cold fusion etc. it’s all theoretical science... a lot of people will berate it for being useless... but remember project Manhattan started from theoretical science too...
