The record

UMM France also supplied customers in France’s overseas territories, from French Guiana to the islands of the Indian Ocean and the Pacific, and the Alter became popular in France with off-road drivers and public services such as fire brigades.

Research status: draft — identification, dates or figures could not all be pinned down; the summary says what is unresolved.

AI rendering impression

An AI rendering impression starts from a 3D model of this vehicle, which an image model then paints into a scene. It is an artist's impression of the type, made to give a feel for the vehicle in its element — not a photograph, and not a record of any particular vehicle.

Proportions, fittings, markings, colours and the setting can all drift from the original in the process. For the vehicle's actual details, rely on the specification, the photographs and the cited sources on this page.
