Playing through WoT bootcamp.
The most critical moment is choosing the reward tank. If you take a wrong tank, the only way to undo this is deleting your account and make a new.

Here are the options:

• U.S.A. tier 3 medium M2 MEDIUM TANK
• German tier 3 light tank Pz.Kpfw. 38 (t)
• U.S.S.R. tier 3 light T-46

You get your tank with 6. sense and enough experience to upgrade most important components.
