From the late 1960s to the early 1970s, like its competitors Panhard also hoped to attract police and gendarmerie forces in addition to armed forces. After the May 1968 uprising in Paris, the need for a dedicated riot vehicle arose.
In reaction, Panhard developed a range of specialized vehicles called “IS” (for “Internal Security”).
Panhard's entry into the VBRG ("Véhicule Blindé à Roue de la Gendarmerie") competition was the M3 upgraded to the VLA/IS standard. (Pic 1 – during trials in 1970)
The Gendarmerie Nationale required 4 versions of the future armored vehicle: "base" (with 56mm grenade launcher, 7.62mm AA-52 machine gun and tear gas diffusion system), "lame" (capable of overcoming obstacles with a bulldozer blade), “treuil” (capable of towing other vehicles) and “PC” (command vehicle). Panhard lost both the VAB and VBRG competitions to Saviem and Berliet respectively.
This version of the M3 was available for export under the name "M3 Police". (Pic 2 – "basic" version)
Algeria purchased 55 M3s, an unspecified quantity of which was still in service with the Algerian Gendarmerie last decade.
These vehicles have been modernized by the addition of various elements from the Berliet VXB-170 such as the panoramic turret (Pic 3) and the front windshield (Pic 4).
Later, Panhard offered the VCR IS. (Pic 5) Although more spacious and with improved mobility, it failed to find any buyer. The prototype was stored underground for many years in the former SHAPE headquarters near Paris. (Pic 6) It could be at the Musée des Blindés in Saumur but I have no proof of that.
