Modern Warfare 3 Weapons, Attachments, and Tactical Equipment Guide

The gameplay is still quite addictive and you are going to spend a lot of time in unlocking different weapons and equipment. This guide will focus on the Modern Warfare 3 weapons, their attachments and the tactical equipment you can take with you during fights.
