I think my opponent first took away the pods as they have to deepstrike, and then split the other half leaving the gargoyles (2 squads) , the tyrants and harpy on board on Turn 1 and deepstriked the Mawlocs and gaunts. The flying creatures deploying as far back as possible and behind cover the first turn (big critters but still got cover).
As we read the rules you get one "grounded" test per squad firing at them, no matter how many actual hits. If it was one grounded test per hit you'd never swoop
