What needs to stand out on the French tank is two things.
It has to look like its from the 30’s. Fit that style etc.
It also has to have a small looking main weapon. Most French tanks didnt go over 75mm guns, or even get close to that number.
The Italian and Japanese tank molds fit that style more than the…
German Tank - An Icon of WWII
US Tank - An Icon of WWII
And the other two tanks look too heavy set and rugged
USSR Tank - The T-34 Monster (although it is in a 30’s style)
UK Tank - Near 1940’s Style, and a big looking tank.
The French tank has to look inadiquite and small. The french doctrine was to use Tanks like cavalry, but that isnt their true purpose, yet there are similarities. The French Tanks were nimble, but too small to breaktrough. They were used to flank german formations, but since the german formations they encountered were tanks themselves, the french were out gunned. The french put their big guns on the Maginot line, in bunkers…tanks that were to big to move. And they split the difference with light tanks.
Armored warfare is not one of extremes, it requires a solid tank, well rounded speed, armor, weaponry. Because tanks are most usefull in formations on their own, with mechinized infantry support sprinkled in.
