Interesting stuff. They sound like revamps of old expansions to be honest. The first sounds like Planetstrike, though with a lot more defensive weapons to use now. And the second sounds like Spearhead, which did allow you to take one Apoc unit if you picked that Formation. Both were fun to play and updating them should see them come back strong.
