I don’t think that is the source of my confusion…
I get that Battleships can fire in each cycle of a sea combat, in both versions. I also get that in both versions a Battleship that takes part in the sea battle part of an amphibious assault cannot also do Bombardment. I’m asking specifically about Battleship Bombardment, and if there is a difference with it for these two versions of the rules.
By my reading:
For 1942.2, Battleship bombardment is a step of the Amphibious Assault sequence, which would only occur once. (Rules page 15)
For Revised, Battleship bombardment is listed as taking place in the opening fire step of each cycle of a land battle, and would take place multiple times in a land battle that has multiple cycles. (Rules page 15)
