Here is the list of weapon proficiencies you can unlock for every weapon in
Call of Duty: Modern Warfare 3.
Unlockable How to unlock
Kick - Reduced recoil.
Range - Increased range.
Attachments - Equip two attachments to the same weapon.
Focus - Reduced flinch when shot.
Melee - Faster melee.
Stability - Reduced sway.
Impact - Better bullet penetration through walls.
Speed - Faster movement with weapon equipped.
Damage - Shells do more damage.
Breath - Hold breath while aiming down the sights.
Remember you could melee faster with Akimbo USP .45s in Call of Duty: Modern Warfare 2? Well you can still do it in Call of Duty: Modern Warfare 3. Just equip USP Akimbo and use your knife, you will noticed that you will be pulling out your knife faster.
How to tell you are host:
Press Tilde (`) or Shift + Tilde. If a Remote Console (or Rcon) shows up. Then you are the host. This is more noticeable with Shift + Tilde because it shows the entire killfeed from the round before.
Ladder - Aim Time:
Prior to climbing a ladder, press the melee button, and then begin to climb. If timed correctly (for example the ladder on Seatown), the character will no longer need to bring out his gun and therefore upon reaching the top of the ladder, the gun will already be brought out ready to fire. This can save time and may benefit in you getting a kill.
