Combined Unit Fire

[XLVIII Pz. Korp]

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.

That is correct. Three units making three rolls on the CRT each with a strength of 10 vs. the target defense.
