For desert operations the AMX-30S has been developed with the following modifications: the fitting of sand shields, reduction in the ratios of the gearbox which limits its speed to 60 km/h and an engine developing only 620 hp at 2,400 rpm. At least one foreign army (Saudi Arabia) has adopted the AMX-30S and its tanks are fitted with a CILAS/SOPELEM M 409 sight. This has a day sight with a magnification of x8 and an 8° field of view, infrared night sight with a magnification of x4.5 and a 10° field of view and a laser range-finder with a range of between 400 and 10,000 m. This development allows the tank commander to range onto a target without having to traverse the turret. In addition the laser range-finder increases the first round hit probability.
