Every year of Call of Duty brings a slight change to the way classes are built, and Vests are one of those changes in Modern Warfare 3. In much the same way as Wildcards from Black Ops 2, Vests allow you to spice up your class outside of the standard picks, so make sure you have one on hand.
How do you choose the best vest for Modern Warfare 3 (MW3)?
The best Vest in Modern Warfare 3 is the Infantry Vest. Currently, there are four vest types available up to level 30 in the game. With the current selections in MW3, the Infantry version is the most versatile by far and can easily boost the effectiveness of any class. I have been using it on all my loadouts and I haven’t looked back.
