Bruiser: “Nearest enemy” mean the enemy or enemies that are in the location closest to Bruiser. If Bruiser is in the street and on the Law’s side Trainee is in the street, Trainee is the “nearest enemy” to Bruiser. If the Law has no units in the street and Sheriff and Lawman are in the building, both Sheriff and Lawman are the “nearest enemy” to Bruiser.
Crazy Carl: Carl’s ability to deal 2 damage can only be activated if he moves to the street as a part of the action. If he is already in the street, he cannot deal 2 damage.
Sheriff: Sheriff cannot be defeated if she is the last Law unit standing and her opponents can only deal one damage. The order of operations would be enemy unit shoots and does one damage > Sheriff shoots > immediate reload after running out of ammo > Sheriff heals > repeat.
