@ghr2:
Example: Uk surface ship in 36, japan has unloaded transports in 36 with units in kwangsi, japan declares war on his next turn, can japan load kwangsi into 36 and attack some some with them?
YES
Normally, it’s not possible, but there is a one-time exception for the turn that you declare war in. Because Japan was not previously at war with the UK, Japan may declare war and load units from Kwangsi into 36 even though the UK surface ship is there.
Not going to take the time right now to show you exactly where it’s at in the rulebook, but it is definitely there.
