I think Otto does a pretty good job describing it right there. But the Germans can make an Officer from HQ then paradrop in Falls. You can get a lot of plane support as well as a plane that land down and you can build Gerbisjagers, pak 36(i think), Sniper, Mg Bike. Once you tech up you can call in 2 Panzer 2's.
The Brits as basically still the brits except you only go up too Field support, Best tank is Stuart.
Everything has new skins as well. They look really good
