In Modern Warfare 4 DMZ, the 3D Printer appears in the Level 1 rewards, the Vendor unlocks at Level 5, the Gunsmith at Level 10, and the Dog Tag Case at Level 20; the Boss Board requires your second DMZ Order. Core FOB tools are ready from the start, but later levels add useful upgrades. Players comparing MW4 options can also review Bot Lobby MW4 alongside this breakdown of station access and progression.

1 How FOB Unlocks Work

The FOB combines preparation stations with a separate 70-level DMZ progression track. Your DMZ Player Level is distinct from your Multiplayer Player Level, and activities such as Story Missions, Dynamic Operations, and Side Ops contribute DMZ XP.

Some tools are available immediately, while other stations require a level milestone or a specific objective. The Boss Board, for example, depends on completing two DMZ Orders, not reaching a particular level.

DMZ XP earned during a deployment still counts if you fail to extract, but unsecured loot and carried equipment may be lost. That makes progression more reliable than your haul, though it doesn't protect the gear you risk in Hajin.

2 Recommended FOB Unlock Priorities

Use the milestones below to plan what to unlock and which later improvements support your next deployment. The FOB also gives you immediate access to several basic preparation tools.

The 3D Printer is listed in the Level 1 reward set, although an earlier FOB overview placed it at Level 2. For the progression path shown here, Level 1 is the listed entry point.

These gates serve different purposes: Orders open target intel, while DMZ levels add stations, capacity, and upgrades. Check both your level rewards and Order progress before planning around a locked feature.

The starting Stash holds 40 general items and 12 weapons, with weapons counted separately. Later capacity upgrades ease those limits, but they don't make every extracted item worth keeping.

3 What Each FOB Station Does

Think of the FOB as a set of connected jobs: choose an Operator, prepare equipment, turn resources into supplies, then review targets before deployment.   

The stations work best when each decision answers a deployment need. Orders can set a goal, while the Stash, crafting, and purchase tools help you prepare for it.

Roster and Stored Gear

Operators manages your Active Duty roster, while Stash/Loadout separates stored equipment from what you carry into Hajin. The Stash is shared across your Active Duty Operators.

Use the Firing Range to check the ranged weapon in your Loadout before risking it in a deployment. The starting storage limits mean you may need to prioritize mission gear, useful weapons, and upgrade materials.

Crafting and Supply

The 3D Printer turns collected resources and ingredients into equipment according to unlocked Recipes. Its options expand through progression, including Tacticals, Lethals, Field Upgrades, and Fire Support.

Survival Kits hold preassembled supplies until opened; opening one transfers its contents to the Stash. Check recipe requirements before a resource run, since a material's value may come from an upgrade rather than immediate combat use.

Purchases and Weapon Preparation

The Vendor sells rotating weapons and equipment, so its stock can help you rebuild but won't guarantee a particular item. Gunsmith lets you configure weapons using DMZ Cash, with attachment access tied to weapon progression.

Weapon Manuals extracted from Hajin expand which weapons you can build. Gunsmith configurations support up to five attachments, while weapons found in the field may have as many as eight; the Level 25 discount reduces Gunsmith purchase costs by five percent.

Intel and PvP Records

The Boss Board provides information on Commanders and Lieutenants after your second DMZ Order. Commander information is available freely, while locating specific Lieutenants can require purchased intel.

The Dog Tag Case unlocks at Level 20 and stores tags extracted from defeated Operators. The Bounty Leaderboard tracks Wanted Operators and Bounty Hunters from the start, while later progression improves claimed Bounty payouts.

4 How to Progress Through the FOB

Build each deployment around a clear objective, then use the FOB to turn its rewards into better preparation. DMZ XP and extracted resources support different parts of that loop.

Before deploying, check your next level reward, Order requirement, or planned upgrade.

● Complete DMZ Orders early when you want structured objectives and progress toward the Boss Board.

● Check Printer Recipes and ingredient needs before collecting materials, so you can focus on resources tied to a planned craft or upgrade.

● Use extracted DMZ Cash at the Vendor when its rotating stock fills a real equipment need; save it when nothing useful is available.

● Extract Weapon Manuals when you find them to expand Gunsmith options, and store weapons you don't want to risk immediately.

Keep preparing while your objective and supplies line up. Speed up when your Operator is ready and the run has a defined goal; pause to reassess if the required gear or resources aren't available.

5 Managing Extraction and Progression Risks

The main risk is committing gear or space to a plan that doesn't match your unlocks. Failed extraction can cost unsecured loot, and the starting Stash limit makes it harder to keep every item for a later possibility.

Check the relevant condition before spending cash, crafting materials, or taking valuable equipment into Hajin.

● Secure gear you can't afford to lose in the Stash before choosing a new deployment loadout.

● Confirm that a station is unlocked by the required DMZ level or Order; XP alone won't meet an objective-based gate.

● Check whether a Printer recipe or station upgrade calls for specific Ingredients, Valuables, or DMZ Cash before using those resources elsewhere.

● Treat XP and carried loot separately: a failed extraction can still add DMZ XP, but unsecured items and equipment may not return.

A conservative plan prioritizes a needed recipe ingredient or mission item and limits valuable gear in the loadout; it suits players building their Stash, but may leave less room for optional targets. A more aggressive run can pursue Lieutenants or PvP rewards, with greater exposure to losing carried equipment.

6 FOB Progression Strengths and Weaknesses

This progression suits players who want clear long-term goals, extra preparation options, and room to improve their storage. It may feel restrictive if you want every station or a particular Vendor item immediately, since access depends on levels, Orders, and rotating stock.

You can reduce wasted runs by checking requirements and securing gear before deployment. That won't prevent losses in Hajin, but DMZ XP still advances even when an extraction fails.

7 Test Your Next FOB Milestone

Before your next deployment, note your DMZ Player Level and the next station or upgrade it unlocks. Also check one specific Recipe requirement or Stash capacity limit so you can see whether your preparation matches your intended goal.

If a station remains locked, check whether its condition is a level gate or an Order requirement, then adjust that one progression goal. If you can't craft or buy the planned item, check the Recipe ingredients or Vendor stock before changing your loadout; adjust one variable at a time.

Next, secure gear you don't want to risk, choose an objective that fits your Operator, and review cheap MW4 Bot Lobby while planning around your next FOB milestone.
