Notes: This Argentine self-propelled howitzer began to replace the Mk F3 howitzers in Argentine service in 1997. It is basically the Otobreda Palmaria turret placed on a lengthened TAM light tank chassis, with seven roadwheels on each side instead of six. The gun has a basic, if uncomplicated, fire control system, capable of direct fire and requiring normal fire solution calculations for proper targeting. This is normally done by an FDC vehicle, but can be done on a portable computer located in VCA-155. Other additions to the TAM hull include long-range fuel tanks and a 5 kW generator to run the system with the engine off.
