Hi,
Some exemple infantry icon for WinSPWW2 :
Germans
 
Germans (Afrika Korps variant)
 
Italians
 
Italians (Desert variant)
 
Frenchs
 
Frenchs (color variant)
 
Americans
 
Russians
 
Britains
 
Japaneses
 
Ingame screenshot (playing with the french)
 
It looks good.
There's a batch file which permit to attribute any icon you want to any nation. (That's the only way to adjust the right nation to the right game's unit because it's hardcoded in the game. The color of the little soldier symbol (in the old soldier icons) seem to depend on a choice made by the scenario creators.
