How to unlock all Mastery Camo in Call of Duty_ Modern Warfare 3

The Modern Warfare 3 Mastery Camos will be familiar to anyone who's been playing the series for any length of time. These special skins are only available to the best of the best—or more accurately, those willing to grind out the often elaborate challenges required to unlock them for a specific gun. 

Each weapon in Modern Warfare 3 can get access to a Mastery Camo, letting you show off your favourite guns and the exorbitant number of people you've killed with them. There are 16 Mastery Camos available in the new game, including four carry-overs from Modern Warfare 2 that have the exact same unlock conditions. So, here's every Mastery Camo in Modern Warfare 3, and what you need to do to get each.
