Its general configuration has been changed in that the engine was moved to the back. Originally it had been intended to give the driver a more central position to improve his view to the right but eventually he remained at the left side of the hull, the right side being occupied by a large ventilation grill. The turret, where the second crew member, the commander/gunner, is located, is also placed left of centre. Two types of turret are being used: the "Modèle réglementaire AVIS-1" fitted with the 7,5 mm "Modèle 1931 Type C" machine-gun and an ammunition stock of 2250 rounds and the AVIS-2 with a 13,2 mm machine-gun. The 7.5 mm version also has a reserve machine-gun that can be placed on a small mount on top of the turret for AA use. If a radio is present it is the ER 29, operated by the commander.
