With transports and inf you can accomplish the same thing and do it cheaper. Buy an AC and then get 4-6 trans depending on your income. With this set up you can unload inf to Fin, Kar, EE, Ger, or WE - lots of territories for you to strike or reinforce, thus Germany must protect them all. Now if you need to get a couple inf to Afr, move your fleet south one (off the coast of Spain) and unload your troops into Alg. Now Ger also has to defend SE for a turn. Also, once you hit 6 trans you can send one down to the coast of FWA to reclaim it, and from there you can send it to South Africa. Germany doesn’t have the inf to defend all of Africa and with 1 tran and 2 inf you can reclaim a lot very easily.
