The central presidency of the German Red Cross (which has a federal structure), the DRK Präsidium, owns a huge number of vehicles directly. Most of these are then given to local branches for general day-to-day use, as otherwise they’d not be run and serviced regularly. Part of this pool is the “Hilfszug” (“Aid Unit”), a humanitarian and medical intervention group part-financed by the German government.
The following would be off-the-shelf ambulances as built by Volkswagen, but note that the DRK Präsidium would have bought them without day-glow red stripes (which would have been added locally).
Mercedes ambulance commonly used in the civil sector at the time … being quite pricey, it should never have been first choice for a strategic reserve:
Ford Transit ambulance – virtually identical to ambulances used by the Bundeswehr at the time:
Ambulance for four stretchers, on an Opel Blitz light truck chassis:
Radiation Detection Vehicle
Personenwagen (PKW) – Utility Cars
