T70 also has wheels. Wheels aren't requirement for any vehicle or tank set. All of them have wheels.
Now back to topic or I call mods
Given your whole case here is saying the 222 Scout Car needs to be buffed because it's apparently not a scout car, the 222 Scout Car's scout car status is completely on topic.
I think we all agree that M3 is a light vehicle and 222 is an underperforming crippled Ostheer light tank so we can move on from this offtopic discussion and rather do something constructive to bring 222 to place where it belong to and should be
Anyone who agrees with Exterior Reptile that the 222 Scout Car's a light tank, raise your hand.
To be frank, 222 is a light tank, not scoutcar because it has a light tank crush, it's entity is bigger than T70 and it's main gun isn't coaxial hmg but a normal cannot that can, unreliably but still, penetrate (even medium) armor.
Once against you're just making things together so it suits you without getting the concept at all.
