Hello, I'm having some trouble with Rule6.22:
Provided his(attacker's) forces are both in supply (from the supply phase) and can trace a valid supply path (9.31), the attacker may assign assets....
So on Turn 1, during the beach landings, I have a valid supply path due to the beachhead but I am not in supply from the supply phase as it has not happened yet. But in the playbook, it looks like you can still allocate assets to the invasion battles. So what am I doing wrong?
Nothing. Since the supply phase didn't happen before turn 1, no one is OOS, so the only thing you have to check for is supply path. If a unit is OOS it should have a marker from the prior turn (I think), on Turn 1, no one has any so you're OK.
