Heavy Fighting in Ready or Not

Aiming for scientific realism in my play, as usual.
Xbox Controller so I can't kill everybody in one shot.
A.I. tweaked to balance the game (increased health and human like aim).
General goal was to make engagements a bit more close to real life combat situations where if combatants are equipped with heavy armor they would usually get multiple injuries before dying.
Also in close combat involving automatic weapons you will rarely see headshots. They are harder to hit and you risk putting yourself in danger from automatic fire if you decide to aim precisely for the head. This is not supposed to be a (cat and) mouse gameplay.
