In my prior analysis, forgot to consider the Russian NO:
Kill 7 infantry, but lose 2 (maybe more), net gain of 5.
Gain 2 IPC, but lose 5, Russia lose 2 IPC (assuming no counter) and gains 5.
So the net infantry gain is 3 / 9 IPC.
Now, you’ll make me believe that the use of these planes can’t make you gain more than 9 IPC somewhere else? 9 IPC is one fighter you lose or 1 extra fighter you kill.
As mentioned, Russians can move in middle east , take persia and Iraq on R2. Take Iraq with 1 tank, 2 infantry, 1 tac. Take persia with 1 mech from the initial setup.
On R3, the mechanized units are back to Caucasus and back into the action for R4 (unless Germany went North). Persia, Iraq and the NO are + 7 of income. The two infantries from Persia replace the infantries lost in Iraq.
If someone attacks G1, I would likely retake baltic using my air power / cheap units in order to protect my North flank. Since I would have more money to spend in the long run, would likely go for a more offensive force (more planes and artillery than normal).
A Sea Lion will most likely be off the map with this tactic, so RAF / UK buys can be a bit more agressive.
The Russian sub would go convoy Raid Norway also…
It would be a fun game to play ;)
