When a player is hit by melee to their extremities (legs, feet, arms and hands) it does the base shock damage with no reduction. For example a light attack with the sledgehammer will do 40 shock damage to the torso and 40 shock damage to the hands whereas an M4 gunshot will do ~96 shock damage to the torso and ~10 shock damage to the hands. This means that a player with melee can target the legs and the arms--or hit them incidentally--of an armoured player and knock them out in as little as 2 shots. I suggest that melee should have shock damage reduction to extremities.
