A new trailer regarding Weapon Proficiency for Modern Warfare 3 has been released

In the video, Mark Rubin and Micheal Condrey walk us through weapon proficiencies. Now, instead of just levelling your player up, you can now level your weapons up individually. Proficiencies help to customise the player's playstyles even further.

They also briefly show off some weapons, and new equipment, such as the Bouncing Betty and EMP Grenade.
