I'd like to see Italians somewhere in there. I feel like they did a lot to hold the allies back in Africa and arn't accounted for in a lot of thinks. They also had a couple of heavy tanks with a few light and medium tanks + Armored Vehicles. Their infantry wasn't well trained but they had some pretty decent weaponry.
Heavy, what a big word. 
Anyway Italian soldiers were well trained, their Officers were incompetent.
But anyway, don't start another history lesson about WW2. 
Well I use the term heavy stressfully

And to some extent yes, Italians had competent and good training, but their key decision making via the officers was poor thus giving the Italian army infamous for being not as good as Mussolini wanted it to be.
No, let's not

Anyway, The Italians and the Japanese are the only large co-belligerent not represented as of yet.
