As anyone else ever considered a SA that granted you victory points for moving past the enemy into thier deployment area, and by abstraction the open sea. We've got a few abilities that mimic the ship that has broken out contacting the enemy.
Some ideas for the sorts of units that might make use of these abilities are German aux-cruisers, in lieu of the long cruise SA German blockade runners, for the run through the bay of biscay Japanese aux-cruisers, same British cruisers, destroyers, aux's making runs to malta ABDA ships, US, Dutch, British ships escaping the overwhelming japanese forces
As a example, Blockade Breaker- If at the end of the turn, this unit is in your opponents deployment area, you may remove it from play. If you do, score # victory points. Your opponent recieves no victory points for you doing so.
