@sharps54 Are you still looking for players? I live in Fredericksburg. We have a group that meets regularly in Woodbridge to play A& A. We usually play a variant called Bloodbath, as well as Global 40, 1914, and Anniversary.
Are we playing with submerging/retreating subs? No submerging subs. Only retreating after a round of combat. But if combat is over, the attacking subs cannot still retreat.
and
Can you place naval units in occupied seazones? No.
