Combined Unit Fire

[Lizardking]

I always thought that when you select say 3 units to fire together for 30 points that was the attack strength and this would be worked out as a single 30 attack. Although I noticed that when you conducted a group attack and eliminate the defending unit, you would have some of your attacking units with no expended points. So that explains why they had points left. So if I understand correctly, the 30 points are worked out for example 10 attack for each unit firing not 30 attack.
