What is your point? I'm well aware of how effective it is from my own firsthand experiences treating wounded soldiers. My point was that it's a specialized form of protection (localized and dedicated to stopping ballistic penetration), not the one-rating-fits-all protection like we see in this game.
Our armor works again bullets to the torso. It still does almost nothing to help against large kinetic transfers (falling, motor vehicle collisions, etc.) and it's only of limited use against blasts (helps against fragments, but not against the pressure wave).
Seeing as it's primary purpose is to hinder bullets from entering your torso and playing merry hob with your insides, I'd say it's working fairly well.
There's definitely room for improvement but it's heads and shoulders above the Empire's gear.
Corpsman or medic?
Point being is that I thought you were dismissing our body armor which is decent compared to the garbbo the Empire uses.
You're comparing real-life existing ballistic protection armour to a fictional armour that you know next to nothing about (in canon)?
Now, if you really want to, you could go on wookieepedia and read what it says there, but the description is much better than what you have alluded to thinking of the stormtrooper armour so far.
