@Cernel said in Pie in the sky idea:
Of course, A&A rules refer only to transports, as being the only attack 0 units. So, you could say it would not apply to attack 0 land units (if they would exist),
Attack zero units exist, for example, in LotR. Hobbits are 0/1, supportable. Shooters are 0/2, giving support. You can send them into battle by themselves, although I don't know what happens if they alone remain.
