Just a follow up question on this. If the attack is on a one of a unit of 4 guys, say the Tarn Viking Warriors. Each guy has a life of 1. If one guy in the unit is attacked and a total of four wounds are received, are all four guys removed from the battlefield or just the one attacked? Also if that guy were to receive 2 wounds are two guys removed or do they all stay on the board until a total of 4 wounds are received. I have read the rules a few times and I can't quite figure it out. It seems logical that the one guy who was attacked is removed and that is all, but I am not sure if that is the right way to play. Thanks in advance for your responses.
Only the character attacked takes the damage. The rest of the squad is fine no matter how many skulls over his defense the attack was. Hense why squads with higher numbers have an advantage even if they have low defense against a hero with a high attack. If the hero has a single attack he/she can likely kill 1 in the squad easily but the squad then gets to take 2-3 attacks on him/her.
