The Soldier's true friend in battle, a Augmented Mirror Shield MK V deflects 82% of all damage away from the soldier. A small amount of this damage is deflected back onto the attacker. This formula cannot be executed on other people. It has the drawback of effectively shutting down your nano capabilities for 2 minutes.
