Weak spots/strong spots on soldier armor

[SGTalon]

I was just drooling on the TR Engie pics and had a thought.

I think i heard that there would be locational damage differences. (i.e. headshots, leg shots, etc)

Wouldn't different features on armor create similar issues? We already have it on the vehicles (Lightning weak on the back) Why not on the personal armor?

That backpack looks pretty beefy. Shouldn't back shots take less damage then? Similarly, that face mask looks very weak. You can see skin! Face shot should be the weakest armor, right?

This could be an interesting thing to spend station cash on too. Not sure if that would be edging into the pay to win thing or not... probably does.

But i think that this idea has some merit.
