MW3 Weapon Proficiencies Guide

The addition of Weapon Proficiencies is the latest in a long line of additions that we are going to be seeing in Modern Warfare 3. And with all of these added extras to the game, it is easy to get mixed up a little on what is what.

The Weapon Proficiencies are much like anything else experienced in the game (or any another Modern Warfare title) in that you will gradually unlock them as you progress. As you become more experienced with a certain weapon, you will gradually unlock all of the 10 proficiencies, one by one.

The easiest way to grasp the idea of Weapon Proficiencies in MW3 is by thinking of it as nothing more than a perk for your gun. While we are all familiar with using perks on our characters, implementing them on our guns is something that is completely new. Let’s say that you are particularly fond of the SCAR-L. If you use it enough, you will soon unlock the first of the Weapon Proficiencies; this being Kick. Here, you have only unlocked Kick for the SCAR-L, for every other gun you still have to get the kills to unlock it.

Below is a list of all 10 weapon proficiencies, along with short descriptions of each one.

  1. Kick
  2. Impact
  3. Attachments
  4. Focus
  5. Breath
  6. Stability
  7. Range
  8. Melee
  9. Speed
  10. Damage

Choosing Proficiencies

Choosing proficiencies depends greatly on which weapons you prefer using, and what type of playstyle you have. You’ll simply have to experiment and figure out on your own. The good thing is the whichever proficiency you choose, you basically can’t go wrong.
