Strat 1: 2-3 transports in Baltic and move Mediterranean fleet west. Usually only feasible if Germany received bid units in Africa, and/or USSR did not take Ukraine (the extra German fighter’s needed on the attack). Threatens invasion of London. Should not be used if Russian fighters landed in Moscow (Allied response: UK 3 fighters and transport E.Can tank, US transport 2 inf 1 art 1 tank (sacrificing US transports) Russia fighters to London resulting in strong UK defense and immediate threat to Baltic fleet.)
Baltic transports can be used to transport German infantry to Karelia as well as threaten London and reclaim Norway. If a united Allied fleet gets close, the Germans can counter with German air plus fodder German transports. However, this strat is not effective against quick Allied air.
Strat 2: Carrier in Baltic. To prevent UK 2 fighter 1 bomber destroying German fleet straightaway. Carrier gives German fighters added range, allowing German threat to London, as well as allowing German fighters stationed at West Europe and on the carrier to rotate duty when attacking Karelia, West Russia, or other points east.
Carrier protects Baltic fleet until the Baltic fleet suicides against the Allied Atlantic fleet. Carrier is much less inherently useful as attacker or defender; its use to effective extend fighter range is of limited use. A carrier is stronger against Allied air, but continued Allied buildup force the Germans to use more IPCs on navy, or lose their existing navy.
Strat 3: Carrier and transport in Baltic. Threatens London and extendes fighter range. As above, but with so many IPCs in the water, Germany’s attack on Russia is stalled.
Strat 4: Nothing in Baltic. The UK has a lot of targets on UK1: retake of Anglo-Egypt, the Baltic fleet, etc. If Germany builds NOTHING in the Baltic, the UK may either attack Anglo-Egypt with less (good for Germany), or the UK may lose lots of air on a risky attack against the Baltic fleet. Either way, the strategy here is to build infantry and tanks, to press on Russia early; if the UK lets its fighters die, that’s just less force the UK can hit the German ground with later.
