Service ribbons are an award mechanic, introduced in GU06 to give small XP awards to players for regular actions. Each ribbon gives 250XP (i.e. 1 cert ), with the exception of the first 5 ribbons per day, which give additional 500 bonus XP.
On completing the requirements of a ribbon, the XP will be rewarded to the player. Players can see all obtained ribbons in the 'Stats' page in-game, with the exception of ribbons for vehicle weapons, which are not yet displayed in the 'Stats' page. The progress until the next ribbon is also displayed when the cursor is placed over the ribbon icon.
All ribbons have requirements that need to be achieved before a ribbon is awarded. Please note that carbines, scout rifles, etc. award a ribbon that is visually identical to that for the Assault Rifle.
