if you’re going to buy anything beyond a G1 carrier, a transport on G2 and G3 is a nice purchase, and it still allows you to build 10+ infantry per round on those two turns. The idea is that you add to your ability to hold/ counter Karelia, and counter landings in Norway. With your 6-7 unit Luftwaffe (depending on whether Russia killed the Ukraine on R1), any landing in Norway can be countered by 6 land units and multiple aircraft. If Norway is not being traded, those German units end up in Karelia instead, causing a headache for the Russians.
The idea of continually contesting Norway/ Karelia is to destroy Allied forces as they hit the ground. The Allied player feels good because German pieces are being killed in Norway rather than against Russia alone- but in actuality Russia is slowly being isolated to fight a 1 on 1 battle against a menacing Japan.
I don’t do this, because I personally can’t pull the trigger on that much German navy- but it is an effective strategy when coupled with an unhindered and well played Japan.Â
By the way, an intriguing antidote to a G1 naval build is 5 US subs. On US4 you can say goodbye to the Baltic fleet unless a substantial contribution was made to it. It also makes the German fleet link up feel a little less secure. Again- I’d go with a carrier, 2 transports and boots personally, but I know a player who does this and wins with it.
The transports in the Med idea is interesting, but it sacrifices the entire north of Europe to the Allies. IMO Germany contesting the north is hugely important. Once Karelia is firmly in the hands of the Allies, things had better be going REALLY well for Japan.
