Japs are just pure mobility - The base building is just insane, they don't actually have an airfield due to almost every unit having Ground/Air capabilities.
Allies are a bit weak overall, they kind of rely on the super weapons (timebomb is wicked). In RA2 we had the Chronotroops in which you could make buildings dissapear etc, they aren't in RA3
Soviets are class, the super powers are very useful, especially Mass Production... Kirov's dominate and the apoc tanks but they are quite late in the game.
The best commando is blatantly the Japs one.
