This is a tough gamble.
It really depends on how R1 & G1 went. If Germany did poorly or average, then UK should go the usual route of trying to build a navy, retake Africa from the west, and invade France / EE.
If however, G did particularly well, and maybe killed all the UK boats, then it’s tough for UK to buy a Navy, if it could just get blasted again… then they have to come up w a new plan.
The India IC is risky… UK has to go all out to hold this, including putting their tranny off FIC (French Indo-China) to block the Phillipines tranny.
2 UK infantry, and 1 fighter tho is risky. Japan can hit that on round 1. (2 inf from FIC, plus 2 fighters & a bomber can all reach India!). If you knew ahead of time this was your plan, then you could play for it by hitting Manchuria hard with Russia on R1, and landing the other R fighter (after using it to attack Ukr) in India.
So R kills one J fighter by capturing Manch. That, combined with the 2nd R fighter going to India can allow UK to hold India on its first turn.
On the 2nd turn, Russia will have to hit Manchuria AGAIN, with the infantry that moved out from Evenki, and 2 fighters. The UK fighters from the UK on UK1 went to Russia… then on UK2, they can attack FIC, or just fly to India for defense. UK will now build 3 inf in India, plus 3 ftrs defending, and they’re pretty strong.
Russia tho is now paper thin on their eastern front, so it didn’t come cheap. Also, Russia has to send all future builds (and eventually pull back their fighters, too) to fight Germany, who will be threatening Karelia from G2.
Combine this with a US IC in Sinkiang, or a US navy / pacific strategy, and it can be quite strong…
