Joseph, I'm not sure what the purpose of note 2 is. Hopefully Joe will chime in. Note 1 just means if all 3 drm groups apply you can only apply 2 of them. The way note 2 reads is if there is armor in the hex you can apply 1 drm from A or B but drms from D and E don't apply, which doesn't make sense to me. I never really noticed note 2 and my initial read of it was that it was just another way to say note 1.
