Korea World at War

For my next World at War game I'm thinking of playing as Korea.

I've played in the Asia-Pacific region before, including as Japan, but never as Korea. In my experience it often dies of Japan or goes inactive, but I am sure it can be played well.

I've read other threads such as Gurbi Tiger's Tips for playing Korea thread and have a decent idea of what to do.

My plan is:

• Invade Mukden, Colonise Kyushu and invade Japan (hoping he's unskilled). Then invade Manchukuo.
• Take Taiwan and the Ryukyus, and Sakhalin. Make a green-water navy capable of defending the first island chain, upgrade from there if needed.
• Conquer China and the Russian Far East. Befriend somebody, ideally a skilled player, in the Australia, India, or the Middle East, split Asia between us. Advance from there.

Land: Light tanks, armoured cars, infantry (or militia and motorised infantry), artillery

Sea: Submarines, battleships (as well as cruisers and destroyers)

Air: Interceptors, naval bombers

Should the strategy be amended, do you have any suggestions on the strategic scale?

Are the units suitable for this purpose?
