Someone should definitely get a picture of some Japanese soldiers in Korea or Manchukuo, sort of the Japanese equivalent of the picture of the Soviet soldiers eating.
Someone should then place the above picture in the summary of Japanese forces, in basically the same format as the Soviet soldiers eating.
Flesh out the summaries of the forces a bit.
Add a bit on the Soviet military theory before the invasion.
Flesh out the results a bit more.
Add a map showing the operation.
Much more on the naval forces and their operations with the 25th army in northern Korea.
Much more on the operations involving and featuring the Amur River flotilla
More on the paradrops, skirmishes and naval landings in Port Arthur and Dairo on the 25th August; when the campaign was mostly over.
