I noticed that there is an achievement for each class for becoming a veteran of the class, but I can’t find anywhere on the net how you would do this.
Anybody know how to become a veteran?
You become a Veteran in a specific class by unlocking every single primary weapon for that class. This unlocks an achievement and the Veteran helmet for that class, equipable from the main menu.
