Destroyer Rules question…

No.  Air units can never capture territories, or land in newly captured territories.

so true

It’s already the case on land, 1 infantry can stop 100 tanks from doing a blitz

as long as they can make it to the Sea Zone the Carrier is placed in.  Yes.  Just move them there in the Non Combat Movement phase.

I do see why they didn’t want to complicate the sub rules w/exceptions and what not, sub rules are tough enough. It would have been easy to add transports must be escorted with surface war ships through enemy sub infested waters or they are lost however. This would have pacified some of us.

Yes. The only units barred from ending the turn in a newly conquered territory are air units.

Thank you for the answer, Kreighund

While I think the SUBs are much improved over Revised OOTB, I feel they are still to vulnerable and not very cost effective.

Do you know if Sub Detection rules or Convoy Raid type rules were ever considered, either during the development or playtesting phase.  I suppose they may have been considered too complex by either WOTC or Mr. Harris, but I do feel this is the one thing that the game is really missing.
