I just got premium, and I want that bow.
But 200 Tank kills? FUCK.
Just play with them a lot, like if you die wait for another tank to spawn before deploying, so all you do is tanks.
Avoid roads and paths where it might make sense for engineers to place mines (and always spam that spot button, you will be able to spot mines from far away most of the time) and try to flank or limit the areas where you might get attacked from. And don't be afraid of pulling out if it seems an area is just swarming with engineers.
Also, active protection is a must have, so use that as soon as you unlock it. Going against another tank that has it will always be rough for you.
