The key to Allies having a chance in OOB is wear down the Axis air forces and to snip out Japanese land units from exchanges with numerous nations.
While that’s happening, a strong force of UK fighters, US bombers/fighters, and a gradually stronger force of Anzac fighters act as a flexible force. A first pressure point is usually India, followed closely by Moscow, and finally the Middle East.
Our options to reduce Axis air and Japanese ground troops.
Adding infantry to Yunnan increase expected losses (must take territory) from 5 to 9 (4 IPC for 3 IPC). Then a soviet fighter takes this to 19.5 (10 IPC for 10 IPC), and a second Soviet fighter takes this to 36 IPC (16 IPC for 10 IPC). So here by spending 23 IPC you force commitment of Japanese bombers and will likely take 2 Japanese planes with you. This remains an attractive target for the Japanese, you definitely do not want to let these planes escape and get back to Moscow.
Now, what are options to take down the German air force? Ideally, what we would do is to tempt the axis player in attacking both 110/111, and getting lift from two scrambles, hopefully trading 4 allied planes against 3-4 German planes (leaving 8-9 German planes on the map). Note that we need to retain enough air power for Taranto.
In order to create further disruption, take the transport from 98 and land one infantry and on AA gun in Greece. This forces Italy or Germany to attack Greece, otherwise any remaining fighters left on a carrier can let the carrier perish first. Hopefully the remaining fleet in the med + Greece will destroy another 2 German planes, bringing them down to 6-7 planes.
This reducing Axis air force business is critical because this air force is a force multiplier, forcing us to build huge navies and armies to invade the continent.
In other words, in early rounds it’s OK to play Rocky balboa and lose 15 IPC of units for each 10 IPC of Axis air units.
So stepping back on the priorities here.
Sub in 98 is critical for Taranto.
The sub in 91 really helps take out 96, we don’t want Italy to have 2 transports.
We spend 23+12 to date so 41, have 9 IPC to spare.
An extra infantry in Paris is causing 4 IPC additional losses, it’s not bad of a ROI and might encourage the Axis player to send the tactical bomber there to avoid a 1 in 200 chance of losing the battle.
With the 6 IPC that remains, it would either be a sub in 110 (further pressure German R1 attack, potentially save the 106 ships), or a combination of one artillery in the soviet far east (to increase the offensive fear factor of this stack) + 2 IPC in the UK bank, allowing a 3 fighter purchase (very needed after the first round).
