M151A2 Fast Attack Vehicle.

The M151A2 cut down for the 9th Infantry Division’s motorised experiments and the Marines in the 1980s: an open frame with a roll cage, a mounted TOW, Mk 19 or M2 machine gun and no doors or windscreen, the forerunner of the Humvee-based and Chenowth fast attack vehicles.

The record

The Army’s High Technology Test Bed at Fort Lewis and the Marines converted M151A2s into fast attack vehicles in the early 1980s with roll cages, weapons mounts and stripped bodies; the Chenowth FAV of 1982 and later the Humvee took the role.

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.
