Yes 2 tanks might not be enough…I find it is important for Russia to have some tanks as well so when necessary, it can run to India for temporary support. Just UK and US planes alone are not enough to support India at first few rounds.
Another nice thing about the 2nd edition is that it has better sculpts: more nation-specific designs, plus anti-aircraft guns represented by specific sculpts.
From the image you referenced, you’re playing the 1st Edition, the forum for which can be found here. OutlawUnForgiven’s comments about air unit suicide missions apply to both editions.
