Etiquette for optional rules vary from group to group, but the rulebook says that they may be used “if all players agree”.
Just to be clear, this is only an optional rule in Classic. In Revised, it’s a standard rule.
Can land units attack sea units?
Can Destroyers attack land units?
If you attack units in an adjacent sea zone to an hostile occupied territory, can the land/air units attack the sea units?
1. Never
2. Only with Consolidated Bombardment, and then only one shot with each amphibious landing
3. Never.
