A second German sub in the Atlantic does pose a problem to the Allied fleet, but I would rather let that German sub do its business against the US and UK, and keep the Russian fighter to trade territories with Germany, than to attack the German sub and lose a Russian fighter to the German counterattack.
sorry to interrupt this thread with a noob question, but I thought subs could only attack other sea vessels, are you saying that it gets a counterattack against an attacking fighter?
That was “counterattack”. It’s probably in reference to USSR using its fighters against German navy on USSR1 before Germany can go, then having to land one of those fighters in Karelia. Germany can crush Karelia on its first turn regardless of what the Allies do. So the USSR doesn’t lose the fighter on the USSR turn; USSR loses the fighter on the German turn when the Germans take the terrritory that the USSR fighter landed in.
