How would I make a custom text decal?

Is it possible to make a custom text decal to use in game ?
I’d like to name one of my favorite tanks.

If so how would I go about it or have someone do it for me ?

Unfortunately, this isn’t possible. The best option is to create a userskin, of which guides to can be found online. These are visible to you only.

Only the creators of partner content have the authorization to create one or two decals (visible in the game) that can be affixed to the vehicles of their subscribers.
