World of Tanks

The original way to unlock this achievement was to use a tank with a single crew over and over again until the crew reaches rank three. Without XP boosts, this could take 300 matches or more. You'll want to pick a tank you do well with, and use every XP boost you can find.

However, it's now much easier. Starting any war story on Xbox one will earn this. Try the first American War story to unlock a crew that's already Rank 3. You can transfer the crew to any premium tank of the same nation and use it in multiplayer match. Also, Many Mercenary contracts will also include a Rank 3 crew.

If you've earned this on the Xbox 360, it should unlock immediately when you get to the garage. If it doesn't, finish one match or war story with your crew of rank 3 or higher.

Since Title Update 4.0: War Stories for World of Tanks, this achievement now unlocks automatically when you start your first War Story.

Of course, you can earn this the legitimate way, by playing a lot with the same tank and crew, earning XP as you go.
