Nation specific SAs isnt a done thing

And neither is expansion a done thing although RB has already done nation specific SAs in the WotC published product.

It looks like we are down to deciding on the version of Air Rescue. Below is the latest summary from AU64 with his recommendation for cost based on the long (multiple unit use) or short (once per game) variant of the SA.


Walrus
Maker: Supermarine
Type: Aircraft - Patrol Bomber
Year: 1939
Cost: ** Based on which Air Rescue version **
ASW: 2
A/VA/HP: 3/4/1

SAs

Sea Basing - This unit can base only in a coast or an island sector on your side of the map. Don't place a Rearming counter on this unit during your Air Return step.
Spotter - At the beginning of your Air Attack step, you may choose an enemy Ship within range 2. Your Ships roll one extra attack die when attacking that ship at range 2 or greater with their main Gunnery attack this turn.

Air Rescue (Cost of unit=5) - The first time a friendly Aircraft is destroyed, score 3 victory points at the end of the turn. You can only use Air Rescue once per game.

Firm believer trying to make this unit fit into the game does more harm than its worth;

 last wasted breath!! can it;; to many useful units yet to do!!!

What do we want to do here?

I am fine with that.
