As the Allies, for a G1 carrier build fleet/G1 Med fleet west:
Depends on how I’m feeling; UK1 either build 3 fighters with UK and unite UK fleet northwest of London and use USSR sub to block G2 Med fleet invasion of London (UK does the usual UK1 stuff, so that’s 2 inf 1 art 2 tank 3-6 fig (built 3 fighters, started with 2 fighters, plus 1 US fighter) defending against 1 inf 1 tank 6 fighter 1 bomber at worst).
Or I build 7 inf 1 trns or sub to defend London and again unite UK fleet northwest of London.
US1 moves northeast of Eastern Canada.
On G2, Germany unites fleet or it doesn’t, and lands fighters at either W. Europe or Norway or both.
If Germany unites fleet and landed most fighters at W. Europe, then Allies build up northwest of UK with Allied fleet of 4 trns 1 sub 1 destr 1 btl plus optional UK2 carrier build. Germany’s fleet is 2 trns 3 sub 1 destr 1 destr 1 battleship, but Germany’s air is out of range.
If Germany does anything else, including non-fleet unification or Norway/W. Europe fighter split or E. Europe/W. Europe fighter split, then the Allies either move in if there’s the opportunity, or the Allies build up another turn southwest of UK (remember, this is if the Germans do NOT park mass fighters at W. Europe, so at most the German fleet is in range; not the bulk of the German air).
Either way, the Germans are forced out of the W. Europe seazone. If the Germans stay, the Allies hit with navy and air, Germany’s fleet dies. If the Germans run, the Allies can drop to Karelia/Arch if the Germans ran to Med, or to Algeria if the Germans ran to Baltic/North Atlantic. If the Germans attack the Allied fleet, the bulk of the German air is never in range (if the Germans beef up Norway fighters to stop Allied navy build northwest of UK, Allies build southwest of UK).
If the Allies want, the UK can build air while US fleet moves ground to Brazil then Africa; this makes the early Allied Atlantic game far more passive, but when the Allies hit, they hit a lot harder.
The Germans can step up aggression in the Atlantic slowing the Allied response by parking fighters on the G1 carrier, but if the Allies stay out of range of the bulk of the German air, they should be OK - meanwhile, with so many fighters out of range of Eastern Europe, and only 8 infantry built G1, Russia can stall for a bit longer than it otherwise might, even after losing a lot of Russian attack force at Ukraine on G1 counter.
