The heavy white line in the Indian Ocean shows where the two theaters meet and governs the movement of naval units, but where is the line on land?
This affects strategic movement of air units from one theater of action to the other.
We would suggest that the line follow the west coast of India, the border of India/Persia, India/Afghanistan, USSR/Tibet, USSR/China, USSR/Mongolia, Balkhash/Novosibirsk, and finally Omsk/Novosibirsk.
Any reprint of the map could easily accommodate the addition of a modified line along the country borders that are listed because of their thickness.
Just another thing to think about.
