not to nitpick, but to maintain consistency with the OOB rules, I would keep it so that sAirbases and Navalbases are considered fully operational if they have 2 or less damage. Making it different amounts of damage for different functions introduces needless complexity. Just my two cents.
You’re right, why add complexity if not needed…
**-Cruisers and Battleships may pick up and drop off 1 infantry unit each during the non-combat movement phase only.
-Operational naval bases may mobilize 1 transport unit each during the mobilize new units phase.
-Operational airbases may launch 1 infantry unit each into a hostile territory 3 spaces away during the combat movement phase.**
