It was very similar in conception but had an enlarged armoured hull, built by Schneider, and a stronger 60 hp Panhard engine.

Citroën would supply the chassis, Kégresse the suspension and Schneider, responsible for the final assembly, the armour plates.

They envisaged the fitting of a specially to be developed Belgian high velocity FRC 47 mm gun to give it a far superior antitank-capacity.

Eventually they decided against obtaining half-tracks and instead bought the French AMC 35 tank to be the recipient of the Belgian 47 mm gun.

Combined with a four-cylinder 3178 cc 60 hp engine in the nose of the vehicle this results in a high maximum speed for the period, of 50 km/h.

There was a crew of three: the commander in the turret and two drivers in the hull, the second facing the back in order to drive the half-track in that direction immediately when ambushed.

The small drums are replaced with three of a very large diameter, the widest in the middle, allowing to climb a 50 cm obstacle.

All vehicles of the type were by this time completely worn out and close to being phased out in favour of light Hotchkiss tanks.

They nevertheless fought with some effectiveness against the invading forces: e.g. on 14 May two P 16's of 1er GRDI were crucial in retaking Haut-le-Wastia from German infantry belonging to 5th Panzer Division.

After the armistice the vehicles in North-Africa were allowed to be used by the French units there, but were transferred to 5e Régiment de Chasseurs d'Afrique in Algiers.
