For some people there are shields with numbers after the nickname. What are they for and how do you get them? Thanks
The shield after a someone's nickname with a number represents his / her tank's percentage protection against your equipped turret.
How do you get the shield thing next to your name, one of my friends got it and he doesn't know how he got it?
