Use the current EOD vehicle names and build the supporting fire, police and medical response before increasing HQ count.
The current names matter
The live UK countryside ordnance mission names EOD Response Vehicles and EOD Medium Equipment Vans. Older guides may expose internal keys such as bomb_disposal_crew and bomb_disposal_equipment. Those are data identifiers, not reasons to tell a player that the required vehicle is unknown.
An EOD Response Vehicle and its equipment support are separate rows. Do not assume that buying one EOD-marked vehicle completes both. For a first land-only expansion, list the exact vehicles and staff for the entry-level mission and confirm the remaining fire, police and medical support can reach the same area.
A verified land-response example
Unexploded WW2 Ordnance in Countryside (829) can use Forest, Farm or Heathland POIs. Its prerequisites include six Fire Stations, six Rescue Stations, ten Police Stations and one Bomb Disposal HQ. The response requires one EOD Response Vehicle, one EOD Medium Equipment Van, two Fire Engines, two Fire Officers, two Police Cars and one Operational Team Leader.
That final support requirement is easy to overlook. The presence of a Bomb Disposal HQ does not mean the account already has the relevant ambulance leadership vehicle available nearby. Check the full response list before commissioning the HQ.
Railway ordnance is another step
The small train-station ordnance mission (834) requires two Bomb Disposal HQs, a HART Base and three Railway Police buildings among its generation conditions. It adds an EIU, PRV, SRV, ambulance and railway-trained personnel to the land EOD response. Its on-scene personnel requirement is one Police Sergeant and four Railway Police Officers.
This should be assessed as an integrated railway-EOD capability, not as an ordinary ordnance mission with a different background image. Use the exact mission record to decide what the second HQ may expose.
Recommended buying and testing order
- Confirm the current HQ menu and land vehicle market before purchase.
- Arrange qualified personnel for the selected EOD vehicles using the live course and assignment screens.
- Complete the response-plus-equipment pair and its local supporting services.
- Test a representative land mission and record any missing vehicle or person message.
- Provide a second usable response or alliance fallback before scaling the HQ network.
- Leave marine activation as a separate decision; land readiness does not establish maritime readiness.
Troubleshooting without wasting purchases
If vehicles are on scene but the call remains open, inspect whether the missing item is the response vehicle, equipment van, command resource or a partner service. Use readable names from the mission page when diagnosing JSON keys in an extension or planner.
When no EOD calls appear, check the live possible-missions conditions, relevant POIs, active extensions and dispatch-centre configuration. Absence during a short observation window does not prove a broken generator. Conversely, a mission already waiting for help is direct evidence of a capability gap that should be fixed before more HQs are added.
