A Rolling HQ That Earns Its Keep in Workshops and Trade Prices
The Mobile Operations Center is a drivable command truck from the Gunrunning update: part mobile headquarters, part specialist workshop, and the launchpad for eight co-op missions that unlock discounted prices on weaponized vehicles.
It is bought from Warstock Cache & Carry, and only after you own a Bunker. Depending on the cab and bays you choose, the finished build runs from GTA$1,225,000 to GTA$2,790,000 at the time of writing.
Its real value is not the truck itself. It is the Mk II weapon upgrades in its weapons workshop, the weaponized-vehicle work in its vehicle workshop, and the Warstock trade prices its missions hand out — savings that repay the buy-in if you run a Gunrunner empire.
Key Takeaways
- A Bunker is required before Warstock will sell you an MOC; the cheapest Bunker starts at GTA$1,165,000 in Paleto Forest.
- The base Phantom Custom package is GTA$1,225,000; the Hauler Custom cab is GTA$1,400,000, and a fully built MOC approaches GTA$2,790,000.
- Three trailer bays hold living quarters or a command center, a weapons workshop, and a combined weapons and vehicle workshop at GTA$995,000.
- The weapons workshop is where standard weapons become Mk II variants with special ammunition types.
- Eight Mobile Operations missions, unlocked by stealing Bunker supplies, each unlock a Warstock trade price when finished as host.
1. Buying One: The Bunker Requirement and the Price Range
The MOC arrived with the Gunrunning update in June 2017, and it is welded to that business. Warstock will not sell you one until you own a Bunker, because the missions, research and supplies that feed the MOC all live in the Bunker loop.
If you are starting from zero, our GTA Online Bunker guide walks the purchase — the cheapest Bunker, in Paleto Forest, is GTA$1,165,000. Budget for both properties together, because an MOC without a Bunker behind it is half a purchase.
On Warstock, the choice starts with the cab. The Phantom Custom anchors the GTA$1,225,000 base package, while the Hauler Custom cab costs GTA$1,400,000. From there, bay choices decide whether you land near the floor or near the GTA$2,790,000 ceiling.
Set against the wider ladder in our roundup of the best businesses in GTA Online, the MOC is best understood as Gunrunning infrastructure rather than a standalone earner — it makes the Bunker business and your arsenal cheaper and stronger.
Timing helps the budget too. Warstock prices across the game are discounted in regular sale weeks, and the MOC is a classic wait-for-a-sale purchase: the Bunker has to come first anyway, so there is rarely a reason to pay full price for the truck in a hurry.
2. The Three Bays and What Each Build Costs
The trailer has three bays, and each bay is a real decision. Bay 1 is either Living Quarters at GTA$145,000 — a spawn point with wardrobe and snacks — or the Command Center at GTA$320,000, which adds the touchscreen that launches Mobile Operations missions and includes the front turret.
Bay 2 can hold a standalone Weapons Workshop for GTA$245,000. The alternative is the combined Weapons and Vehicle Workshop, which spans Bays 2 and 3 for GTA$995,000 and is the build most owners end up choosing, because it keeps both workshops in one trailer.
Cosmetics and teeth come on top. Trailer paint schemes cost a flat GTA$115,000, and the full front and rear turret set runs to GTA$210,000 — but the turrets only unlock through Bunker research, so money alone cannot buy them on day one.
Build advice is simple: Command Center plus the combined workshop is the functional MOC. Living Quarters and a lone weapons workshop save money now and cost you a rebuild later.
Think about which half of the truck you will live in. Mission runners need the Command Center above all — without it there are no Mobile Operations and no trade prices. Arsenal builders can start with the Weapons Workshop alone and add the vehicle bay when the weaponized fleet arrives.
3. The Workshops: Mk II Weapons and Weaponized Vehicles
The Weapons Workshop is where six standard weapons convert into their Mk II variants, each opening up dozens of attachments and special ammunition — explosive, incendiary, armor-piercing and hollow-point rounds among them. For many players, this workshop alone justifies the truck.
Our overview of GTA Online weapons workshops compares where each upgrade family lives. The MOC's bench is the original home of the Mk II line, and it remains the one tied to the Gunrunning career.
The Vehicle Workshop modifies weaponized vehicles — fitting and upgrading their guns, armor and countermeasures — and it can convert an Insurgent Pick-Up from a Pegasus vehicle into a stored personal vehicle, which no ordinary garage can do.
One famous exception: the Oppressor Mk II cannot be stored or upgraded here. As our guide to the Pegassi Oppressor Mk II in GTA Online explains, that bike belongs to the Terrorbyte — a later truck built for exactly that job.
4. Mobile Operations Missions and the Trade Prices
The Command Center touchscreen launches eight Mobile Operations missions, run by Agent 14 for two to four players: Severe Weather Patterns, Half-track Bully, Exit Strategy, Offshore Assets, Cover Blown, Mole Hunt, Data Breach and Work Dispute.
They unlock through your Bunker supply runs — specifically supplies you steal, not supplies you buy. The ladder runs Severe Weather Patterns at 2 stolen resupplies, Half-track Bully at 4, Exit Strategy at 6, Offshore Assets at 8, Cover Blown at 10, Mole Hunt at 12 and Data Breach at 14, with Work Dispute opening once Data Breach is complete.
The mission pay itself is modest — guides put a typical run at around GTA$22,000 for fifteen minutes or more of work. Nobody grinds these for the cash. The prize is that finishing each mission as host unlocks the trade price on that mission's weaponized vehicle at Warstock.
Those trade prices cut serious money off vehicles like the ones the missions showcase, and they never expire. Run each mission once as host, with friends filling the seats, and the MOC has paid a large slice of itself back.
Once unlocked, a mission stays on the touchscreen for good. Owners replay them to help friends through the same list — remembering that the trade price only lands for the player hosting on their own MOC, so every owner needs one hosted clear of each mission.
The later Terrorbyte and its Master Control Terminal centralised business management in a similar truck — but it never replaced these missions or their trade prices, which is why the MOC still gets bought today.
5. Living With It: Storage, Calling It In and Losing It
A personal vehicle storage bay lets you keep one vehicle inside the trailer, ready wherever the truck is parked. You request the MOC itself from the Interaction Menu under Services, and it spawns nearby rather than at a fixed garage. With living space fitted up front, it can also serve as a spawn point, which makes it a practical base between Bunker runs.
Driving it is a deliberate experience: the cab and trailer are heavy, the turrets are crewed by passengers rather than the driver, and the whole rig is built to be parked and worked from, not raced across the map.
If another player destroys it, the MOC dissolves instead of exploding. There is no insurance fee for you and no bad-sport style penalty cost for the attacker, and you can request it again from the Interaction Menu straight away.
That forgiving loop is the point of the vehicle. Park it near your Bunker, run your research and supply rhythm from it, work the workshops between missions, and treat the truck as the Gunrunning business's front office.
The two properties genuinely feed each other. Bunker research is what unlocks the trailer turrets and some of the Mk II hardware the workshops fit, while stolen Bunker supplies open the missions the Command Center runs. Owning one without working the other leaves half the system switched off.
Frequently Asked Questions
How much does the Mobile Operations Center cost?
Between GTA$1,225,000 and GTA$2,790,000 depending on build. The Phantom Custom base package is the floor, the Hauler Custom cab is GTA$1,400,000, and bay choices — especially the GTA$995,000 combined workshop — decide the final figure.
Do I need a Bunker before buying the MOC?
Yes. Warstock only sells the MOC to Bunker owners, and its missions and turret unlocks are driven by Bunker supplies and research. The cheapest Bunker costs GTA$1,165,000.
What is the difference between the Phantom Custom and Hauler Custom cabs?
Looks and price. The Hauler Custom is the more expensive, boxier cab at GTA$1,400,000; the Phantom Custom anchors the base package. The trailer, bays and workshops behind them work the same either way.
Where do Mk II weapon upgrades come from?
The MOC's Weapons Workshop converts six standard weapons into Mk II variants and fits their attachments and special ammunition. Later workshops in the Avenger and Terrorbyte offer the same bench, but the MOC is the original.
Can I store the Oppressor Mk II in the MOC?
No. The Oppressor Mk II can only be stored and modified in the Terrorbyte's specialized workshop. The MOC's vehicle workshop covers the other weaponized vehicles in its class.
How do I unlock the Mobile Operations missions?
By stealing Bunker supplies. Purchased supplies do not count. Missions unlock in sequence from 2 stolen resupplies up to 14, and Work Dispute opens after Data Breach is completed.
What are Warstock trade prices and how do I get them?
Trade prices are permanent discounts on weaponized vehicles. Finishing each Mobile Operations mission as the host unlocks the trade price for the vehicle tied to that mission.
How many players do the Mobile Operations missions need?
Two to four players. They are co-op jobs launched from the Command Center touchscreen, hosted by the MOC owner, with Agent 14 running the operation.
What happens if my MOC gets destroyed?
It dissolves rather than exploding, with no fee for you or the player who destroyed it. You can request it again immediately from the Interaction Menu's Services list.
Is the MOC still worth buying today?
For Gunrunners, yes — the Mk II workshop, the vehicle workshop and eight permanent trade prices still repay the cost. Players who never touch the Bunker business will get far less from it than from a Terrorbyte or Avenger.
Closing Thoughts
The Mobile Operations Center is a specialist's purchase: wasted on players who ignore Gunrunning, close to essential for those who run it. Buy the Bunker first, choose the Command Center and the combined workshop, steal your supplies to open the missions, and let the trade prices quietly repay you for years.
