The CAESAR (CAmion Equipé d’un Système d’ARtillerie; French: Truck equipped with an artillery system) is a French self-propelled 155 mm/52-calibre gun-howitzer, installed on a 6X6 truck chassis. Examples built for the French Army use a Renault Sherpa 10 chassis, examples built for export utilize the 6×6 Unimog U2450L chassis. The CAESAR platform was developed by the former GIAT Industries (now known as Nexter) and is operated by the French, Indonesian, Saudi Arabian, and Thai militaries.
