First things first…
Type 2 Ke-To did enter production and 34 of them were built.
Now before I describe the Ke-To, it’s important to understand that the Type 98 Ke-Ni in War Thunder / Enlisted isn’t even the production version of the Ke-Ni. The Production Ke-Ni had 16mm of armour and better designed hull instead of that 12mm thick rounded hull.
Type 2 Ke-To only differes to the production Ke-Ni in 2 different ways.
Whilst the chassis and hull is 16mm thick and identical to the Ke-Ni Production, the turret was changed with an enlarged one since the one on the Ke-Ni wasn’t found to be ideal. The second change is the use of the better Type 1 37mm (800m/s) instead of the 37mm Type 100 cannon (700m/s)
