About Sherman Radio Net, what does the levels mean? Does it mean that the buff is increased or stacked due to multiple tanks nearby, or that it simply tells you 1-3 nearby tanks are granting a flat buff?
Seems how it works is that if you have a vet1 Sherman, it gains Radio Net buff if other medium tanks are nearby; levels 1-III according to 1 or more nearby tanks. Are the reload and sight bonuses good enough to justify needing nearby medium tanks just for the Sherman to get the buff?
The bonus is multiplicative, so it'd be 0.9 ^ # reload speed and 1.05 ^ # sight radius for # additional vehicles within the aura.
