For the last Combat Training course, you can gain weapon experience from hitting opponents with you weapon, which can lead to a max increase in 25% dmg/acc increase.
My question is; does the benefit only apply to that weapon, or to all weapons in that class, eg getting exp from a M1 Tactical and it rolling over onto the Jackhammer?
From my understanding it was just for that weapon not the entire class and not specifically that exact weapon instance (meaning you can use any M1 tactical). This is supposedly gonna change pretty soon though, with the new updates you'll be gaining experience with specific instances of a specific weapon. I could be wrong though
The moment you have finished the Bachelor of Military Arts and Science you gain experience on each weapon you use in combat.
Primary, Secundary and Melee. Only weapons you dont built up experience in are the Temporary ones.
Correct each individual weapon builds experience.
