First of all you need a new gaigin account. So if you've played war thunder or something else you need another e mail. The first three tasks are winning battles. I recommend choosing a shotgun car because they're easy to use. Don't focus on levelling up because that will only make your opponents stronger. Callouts are key, I started using callouts and went on a ten game win streak.
