This isn’t really a “problem”. They are supposed to be like that, it’s the way they made the game. The Axis both share the same sculpts and the Allies all share the same sculpts.
If you check you will also find the Japanese fighters are FW 190s and the Japanese bombers are He-111. Also, all the German ships are Japanese models (Akagi carrier, Kongo battlecruiser, etc.)
Same with the Allies. All three use the IS-2 tank (Russian), P-40 Warhawk fighter (USA), Lancaster Bomber (British) and so on.
WOTC did this to keep this game cheap in cost.
It’s a situation which has happened in earlier games too, though not to the extent of the 1941 game. Most games for instance have given American submarines and transport ships to Britain and Russia, and up till the new edition of AA1942 the UK and the USSR also got American howitzers as artillery pieces. Britain got American Sherman tanks before it received its own Matilda tanks a few games ago – which at least makes historical sense, because in WWII the US did indeed supply the British with Shermans. Some of the other foreign-equipment situations we’ve seen before, however, have been laughable: the Italians using combinations of German and Japanese equipment in Anniversary, and the French using the same pieces as the Russians (including Russian-design tanks, battleships, cruisers and destroyers) in Europe 1940. The 1941 game is the first one, though, in which the Americans have had foreign equipment, the funniest example of which is the use by the US of IS-2 Russian tanks, which are named after Joseph Stalin.
Allright i understand what you guys are saying, however in the rulebook if you look on the page “unit profiles” the Japanese tank is different. It shows a small Japanese tank with a short gun.
