A target system for light infantry weapons including a target overturnable by an impact and an actuating mechanism configured to move the target. The target is connected to the actuating mechanism via a pivot structure. Further, the actuating mechanism includes a lifter configured to lift the target to a substantially upright position, a vertical rail system and a carriage vertically moveable along the vertical rail system, and an electric motor configured to move the carriage along the vertical rail system. Also, the pivot structure is arranged on the carriage, and the lifter includes a supporting lifter device, against which the target falls when hit and which, when the carriage is lowered, lifts the target to the substantially upright position utilizing the movement of the carriage and an inertia of the target. In addition, the target system is portable and of modular construction.
