Tactical should gain support from cruisers.
Cruiser should cost 12, but is supportable by battleships.
Carrier works good already.
Battleship should have a new ability. Flaggship: Support cruisers like artillery support inf and increase both their attack and defence by one.

At the end of combat sequence, each defending transports who is not destroyed may choose to roll a die, scoring an escape on 3 or less. The tranny is then be moved to any adjacent seazone and is removed from combat.
If all adjent seazones is occupied by any sea or air units its impossible for trannies to escape.
Airbase can produce one air unit if undamaged.
Navalbase can produce one sea unit when undamaged.
And another edit: Fighters intercept at 2 or less :)
