A question about retreats and suicide missions:
Imagine two of my fighters start at my airbase in Dutch Guinea. They fly five spaces to SZ 6. It is possible because my empty carrier moves there, too.
Actually, your carrier is not required to go to Z6 in combat move. It must only be POSSIBLE to get there in noncombat movement. If there are planes surviving and the carrier can get there in noncombat (may not be able, if an attack failed to clear the way), then you are required to send as many carriers as necessary to pick up survivors. If you CAN pick them up, you MUST.
Along with 10 Battleships or something. Imagine further that for some reason I occupied Korea. Now the battle begins because there are 123 enemy ships.
May I retreat my Carrier?
What happens to my planes?
splish-splash they are taking a bath in Z6
I suppose the planes will be taken out of the fight, but remain in the same zone?
They will die?
Only the pilots will die. The planes will sink to the bottom of the ocean.
They are not allowed to move to Korea as, say, units scrambling and using their home base are allowed to?
Correct, not allowed to move any more. It is on DEFENSE that planes get a movement point to land after being displaced from a carrier or scramble or intercept, what have you. Not on offense.
I am allowed to retreat the carrier even though that will doom the fighters?
I cannot retreat the battleships and leave the carrier (or the planes) fighting?
No. Everything must retreat together.
See my first comment. You do not have to move the carrier into Z6 to join the battle in the first place. But if you retreat, the planes will be stuck in Z6 with nowhere to land and will be forfeited (because they have 0 remaining movement after flying the full 5 spaces)
Please feel free to ask follow up questions if you need
