I'd like to know what happens when a damaged unit is defending an area. For example if I was the attacking player and was attacking my opponents battlefield zone with Ironclaw's Horde (CS 58) power 4, Crooked Teef Goblins (CS 56) power 1 and Doom Divers (CS 65) power 2, a total of 7. And my opponent is defending their battlefield zone with Mountain Brigade (CS 11) HP 6 but it has taken two damage already.
Do I have to……
1. Assign 4 more damage to the Mountain Brigade bringing the total to 6 damage (enough to destroy them) before I can apply damage to the battlefield Zone.
2. Assign 6 damage equal to its printed HP, before assigning damage to the Battlefield Zone.
The other question I have is
If my battlefield zone is burning and my opponent attacks it, do I have to defend with my units. I know he cant do any more damage too that zone but if I don't elect defenders nothing happens. And vice versa if I attack his battlefield zone and he doesn't allocate defenders I can't destroy his combat units. Is this within the rules?
Any help is much appreciated
