I don’t see much value in the 70 IPC of Trn once you take London and get your offensive units back on mainland Europe.Â
Spending resources to address their protection seems less efficient than boots on the ground pushing back the Russian advance.
5 Transports and the fleet stay in the Baltic Sea - now you can ferry your infantry/artillery builds directly into Novgorod each round (+13 units a round in Novgorod - there’s not a snowball’s chance in hell Russia is getting it back - ever.)
5 Transports go down to Gibraltar - land in Morocco and join with large Italian fleet - which will probably exist unless England went no defense for England - and take Brazil, Africa, W. Indies and then slide the rest down around the Cape for Madagascar.
There’s a lot of things you can use the transports for. You could use them to set up a train service to Arkhangelsk through the Arctic Ocean and the other half to shuttle troops from Berlin.
