From the USSR we have a T34/76, a PE 8 bomber and a YAK fighter - again, the destroyer, submarine, transport and artillery piece are courtesy of the USA.
The first of the Germans. A Graf Zeppelin class carrier, Bismarck, a type 34a (Z5) destroyer, a type 7 U Boat and a Danzig transport type.
A Ju 88 and Ju 87 Stuka together with a Panther tank and an 88m deployed in this AA configuration. Fortunately there is a 105mm howitzer and a Me 109G in the next set I am getting (Spring 1942). The 1941 set features a Tiger 1 (as well as a JS2) and earlier Panzers are available - as well as shielded 88mm - from the suppliers mentioned in my previous post.
For Japan we have the carrier Shinano, the mighty Yamato, a Fubuki class destroyer, an I class submarine and a Hakusan Maru class transport. You can get a Kongo class battle cruiser and an Akagi class carrier separately to expand the selection somewhat.
A Betty bomber, a Zero fighter, a type 95 Kyugo light tank and a 70mm howitzer. The tank is quite a nice model and I reckon it could double as a Panzer 38t with a German paint job.
The generic AA gun and an industrial complex aka a target.
