(A side from the Armorsport discussion over in featured documents)A little research on wikipedia shows that the Type 95 Ha-Go lght tank could and did do pretty well against other light tanks -- M2-M4 Stuarts, Russian BTs, British Vickers, and even (Chinese-owned) Panzer I's.
Its biggest claim to fame, however, was its ability to get into places where nobody else thought a tank could go.
It would also be a fan favorite in the light tank races. Not because it's fast, but because it has such an incredibly rough ride that it's a lot of fun to watch it bounce... :-)
The Type 97 medium, however, was totally outclassed by the Sherman and T-34's didn't even notice them...
