Just playing the purple boss battle, its simply impossible to get any unit landed on the moon as it just stacks fighters and bombers everywhere. and the unloading mechanic is just not cutting it. If I mass astreus with say 200 AA units, sneaking past the orbital fighters, they just don't land efficiently enough. it also seems air units are able to target the units loaded in the astreuses, even when in orbit... I advocate for enabling the avenger by default, and adding an AA satellite would help a great deal as well.
