I will eventually buy out the Sally training units and use them in combat training in Asia, I think. Same with the 2 Ann units that need upgrading. That will leave me with only a few 1E units left for some backup training.
I am using IJN units for ASW, though later in the war I will need more of them and less ground bombing so will transition some units to ASW. I skipped the Helen-I entirely, so no MAD in the IJAAF for me.
Edited to include screenshot. As you can see, I'm only producing the Helen IIa. You can also see that my losses up to 8/15/42 haven't been terrible - averaging just under 2 bombers per turn, most of that front-loaded in the DEI/SRA. You can also see that I'm researching the Peggy-T and Tsurugi.
I have the luxury of playing with PDU On, so don't need to build anything else. This means that pretty much all of my build need will be filled with Helens. I'm including all of this info in case it is of use to you as a reference point... Just keep in mind that our games could be wildly different and I could be totally wrong [:)].
