How does transporting units across sea work? Can airborne transportation be done?
Also, as Germany, how do you use your u-boats effectively against convoys? I skimmed a bit in that nice strategy/info pack stickied, which mentioned that squads of 3-4 are effective; but more specifically, do you just park them around a convoy (the thing also mentioned an attack occurring when the convoy tries to move through) in order to avoid detection from an attack you initiate? And since you start with only 2 u-boats (I'm playing vanilla), do you end up waiting until a certain point where you're able to produce another or two before you start raids?
Anyhoo, thanks in advance
