All DMZ upgrades and how to unlock them

Season four of Call of Duty made plenty of changes to Modern Warfare 2 multiplayer and Warzone on June 14, but DMZ got some of the most significant updates and upgrades of any of the game’s popular game modes.

In particular, players have a whole collection of new upgrades to unlock now.

A pivotal part of the new DMZ features is the Forward Operating Base, or FOB, complete with numerous upgrades that will improve the ways in which you can prepare for deployments and unlock new goodies. Increases to stash sizes, more insured weapon slots, daily urgent missions, and more can be unlocked via the new progression system.

Here’s a look at all the DMZ upgrades introduced in season four and how to unlock them. This is a work-in-progress guide and more details will be added upon completion, so some upgrades may be missing additional necessary tasks that have not been unlocked yet.
