How the Forward Operating Base Works in MW4 DMZ
Every DMZ run starts and ends at the Forward Operating Base. The official Call of Duty Deep Dive, published June 6, 2026, frames it around three pillars -- preparation, progression, and long-term squad support -- and describes it as both a services hub and a social staging ground where squads regroup, rearm, inspect Operators, and help onboard newer players before infil.
One detail the blog states plainly: the FOB is not fixed. As you earn XP, complete Missions, and move through the Trait System, it "evolves alongside you," unlocking functionality and visually transforming as you go. The Deep Dive stops short of showing what each tier looks like, but the link between your progression and the hub's growth is stated directly.
Rather than walk the stations in menu order, here is how they group by what you actually use them for.
The economy: earning and spending
Your Wallet holds in-game cash, and Missions and Ops are the primary source -- earnings wire straight to it. Cash covers weapons and Gunsmithing attachments, rescuing MIA Operators, and buying Lieutenant Intel. The Deep Dive also notes a wrinkle: you can run an Active Duty Operator as a cash mule in specific high-value situations like vault breaks, HVT kills, and Dynamic Ops.
Spending happens at two counters. The Gunsmith sells weapons and attachments -- more effective gear costs more -- and supports up to five Attachments plus an Apex Attachment per weapon, though the blog separately confirms eight-Attachment weapons inside Hajin. Weapon progression carries across both Multiplayer and DMZ. Alongside it, the Weapon Vendor offers a rotating, limited selection of specialized weapons that refreshes periodically.
The gear loop: crafting and storage
The 3D Printer turns resources you gather in the field into functional equipment -- the blog confirms NVGs, ballistic vests, backpacks, consumables, and Killstreaks, with recipes unlocking over time. One firm limit: it does not manufacture Primary, Secondary, or Melee weapons. Those come from the Gunsmith and Vendor, keeping crafting and buying as separate lanes.
What you keep between runs lives in the Stash, a persistent inventory of weapons, equipment, consumables, and valuables split between the Stash itself and your Active Duty Operator's Backpack and Loadout. Stash size grows as you rank up, and a Free Loadout option exists for jumping straight into a deployment.
Prep and planning
Orders and Objectives is the mission desk -- active Missions, completed objectives, rewards, and planning your next operation. The Firing Range gives you a first-person space to test Primary and Secondary builds before committing them to a run. And Active Duty / Operators manages your roster, including Operators awaiting recovery after a failed exfil; each one carries a persistent Backpack, Loadout, and Trait Tree.
The hunt and the risk
Two stations deal in danger. The Boss Board tracks hostile Lieutenants: pay for intel to pinpoint them, or climb Hunt Towers in the field to find the nearest one. Kill a Lieutenant and they drop Dog Tags that populate your Board -- but the Deep Dive is clear those tags cut both ways, staying trackable and valuable to enemy squads hunting you. The Bounty Leaderboard extends that tension, surfacing the most dangerous rival players active in the Exclusion Zone.
When you are ready, Deploy handles infil through the Paid Infil System -- a quiet approach on foot, or a faster, louder entry by helicopter or plane, with an optional vehicle drop.
Still unconfirmed
The Deep Dive does not detail how many FOB upgrade tiers exist, what the Trait Tree looks like at each Operator level, or the full Weapon Vendor rotation. Imagery of the FOB is promised at a later date.
