Actuators in precision guided munitions must provide precise, reliable movement of control surfaces; the three main families are hydraulic, pneumatic, or electric servo mechanisms. The best choice is electro-servo actuators because they pair an electric motor with closed-loop servo control, giving precise position and speed with real-time feedback. This arrangement delivers accurate, repeatable surface movement essential for guiding the munition, while avoiding the weight and plumbing needs of hydraulics and the simpler, less controllable behavior of a plain electric motor. Pneumatic pistons are another form of pneumatic actuation, not the third option beyond hydraulic and pneumatic systems, and hydraulic pumps are energy sources that power hydraulic actuators rather than stand-alone actuators themselves.
