@Constantinople:
But if there is no destroyer, isn’t there still an Opening Fire phase?
Technically, no. The subs get to fire or submerge before everything else, but it’s called Surprise Strike now. There is no Opening Fire phase, but it acts the same way.
The difference is that in Revised subs always fire in Opening Fire whether there’s an enemy DD or not. The casualties just aren’t removed immediately if there’s a DD. In AA50, if there’s a DD, subs fire at the same time as everything else. It’s a subtle difference, but it affects how sub casualties are chosen.
@Constantinople:
Also, isn’t the no air attack w/o a destroyer the same?
No. Air units can hit subs without a DD in Revised. You’re thinking of Europe and Pacific.
@Constantinople:
Weren’t the bombardment casualties allowed to fire back before?
No. In Revised, shore bombardment occurs in Opening Fire, so the casualties are removed before their turn to fire.
@Constantinople:
Has the way that planes travel with carriers changed?
Can planes stay on a non attacking carrier when that carrier moves?
Nothing in fighter/carrier interaction has changed, except for mobilization of new units. You can place a new fighter on an existing carrier in AA50 when you mobilize units. Also, when mobilizing a new carrier, in Revised you can move an existing fighter from the IC territory onto it, whereas in AA50 that fighter has to end its movement in the sea zone where the carrier will be mobilized (same as in LHTR).
