World of Tanks

You need to use a Tank(Light, Medium, or Heavy) and destroy and enemy Tank(Light, Medium, or Heavy) that is at least 2 Tier's higher than your own. (Your tank is a tier 5, enemy tank Tier 7 or higher)
(NOTE: This has appeared glitchy for some people, mine popped instantly when I did the above, but it might be different for some people or not unlock)

I tried for quite a while unsuccessfully to get this, and finally ending up in a match on Himmelsdorf using my US Tier 6 M4A3E8 to take out a Tier 8 US T32. It's possibly my favorite kill of all time with how it happened, and the brief video is below.

All I can really suggest is try harder to get this achievement when you're using a tank that is fairly maneuverable(a slow tank will just get slaughtered against higher tiers), and try to steal kills or do a lot of sneak damage. Another excellent option is going after enemy artillery with a speedy tank such as the US T2 Light, or the Russian BT-2 or BT-7. I never got that to work though as I always was killed first.

I just played a match with my M12 - a tier 7 American artillery.

I killed all 3 enemy artillery, one of which was a tier nine, as well as a tier 7 TD.

I did not get this achievement, nor this one:



Therefore one or more of the below must be the case:

1. The achievement is buggy (wouldn't be the first time)

2. You cannot get this achievement while playing as artillery.

3. Enemy artillery kills do not count towards either achievement.

Because of that I would recommend playing as a high penetration/damage TD. Hang back and try to steal a kill of a tank that is 2 tiers higher than you.

Since this is a new achievement can people please let me know how you got/get it and I will update this solution
