As you progress through the game you will unlock numerous achievements and each will reward you with a stripe, a mark or a badge. Those three elements combined will allow you to create your own personal banner:
The achievements are usually awarded for killing a number of AI or human enemies with a particular weapon or weapon type or doing particular actions on certain maps. Some of them are extremely challenging. Earn these achievements, and you can show the world that you are a real Warface: Clutch warrior!
You can also buy some of the banner elements in the in-game shop, for instance, a selection of national flags. The range of items to show off on your profile in the in-game shop is constantly expanded, so check back in store to see what's new after every major update!
