Small Tank Trophy
Complete 10 levels.
You can freely choose which of the 60 available levels you want to complete. I recommend just doing the first 30 but if you get stuck on a level, feel free to skip it and do another one instead. For tactics I recommend trying to stay in cover if possible and take potshots at the opposing tanks. This because they have quite good aim and you die in one hit.
