How heavy do you think sineva's shield is?

Let's take in game feats.

In warfare, i one tank three consecutive point-blank shots from the battle tank before dying.

So that shield must be made of antimatter or something. Or just game login.

Also that shield would not even get a dent from the M82 Sniper rifle, which can punch through tank's armour.

It can tank both of vyrins C4 stick on it. Or D-Wolf tripple blaster.
