A marine extension adds dedicated EOD vehicles and substantial maritime support requirements.
Separate the land and marine rollout
A marine EOD extension should be commissioned only after the coastal response it depends on is usable. Our recommendation is to treat the decision as a new service package: specialist EOD response, marine equipment, command, Coastguard teams, vessels and supporting police and medical cover.
This is especially important for a land-focused account. Buying marine capability simply because it appears beside a completed land expansion can create demand in a service branch the player did not intend to operate. Check the mission changes and decide explicitly whether the new branch fits the account.
Harbour ordnance: the actual vehicle names
Unexploded WW2 Ordnance in Harbour (832) lists three Bomb Disposal HQs, two Marine Unit Extensions, nine Coastguard Rescue Stations, one HART Base and one active Drone among its prerequisites. Its marine specialist response comprises two Marine EOD Response Vehicles, one Marine EOD Equipment Van and one EOD Commander.
The same incident separately asks for an ILB, an ALB, two Coastguard Rescue Vehicles, two Coastguard Commanders, one Coastguard Support Unit and a Drone. Police, a Fire Officer, ambulance, HART and supervisory personnel also contribute. A generic land EOD group is not the published response.
Recommended readiness sequence
- Inspect the mission variants opened by the marine extension before activating it.
- Confirm current marine vehicle availability, crew qualifications and any transport relationship in the live UK interface.
- Check both required lifeboat classes are staffed and dispatchable from the intended coastal area.
- Prepare Coastguard command and support without exhausting ordinary shore response.
- Include Drone dispatch and the separate active-Drone generation prerequisite in the test.
- Run one representative marine incident while preserving a usable land EOD fallback.
Geography and fault diagnosis
The harbour mission explicitly allows Ocean and Regular vehicle groups. If a boat cannot be selected, check the current mission variant, allowed vehicle group and actual dispatch state. Do not immediately replace it with a differently named vessel: that may create a second mismatch.
Position shore support around practical road journeys to the same harbour area. Map proximity across an estuary can be misleading for land vehicles. A coastline-wide service needs several complete response groups or a deliberate reinforcement plan, not one distant equipment vehicle relied upon by every station.
When an incident stalls, examine EOD vehicle rows, vessel rows and personnel rows separately. Record the exact message and URL when reporting a suspected issue. Old forum reports about inaccessible boats establish that someone encountered a problem at that time; they do not establish that the current game is still broken.
After completion, check which scarce resources remain committed elsewhere. A second marine incident can reveal a shortage that was hidden when you tested only one. Fix those repeated bottlenecks before adding another generator.
