A method and a system for providing a sighting reticle oriented to aim at a target from a vehicle within an environment of the target are described. The method improves the situational awareness of the operator regardless of the orientation and motion of the aiming instrument. The method comprises providing a graphical image representing the environment seen from the vehicle when aiming at the target; determining a state of the vehicle with respect to a spatial reference point; overlaying the sighting reticle onto the graphical image, the sighting reticle indicating the target on the graphical image with respect to the spatial reference point, the sighting reticle comprising a marking defining the spatial reference point; positioning the sighting reticle to orient the marking based on the state of the vehicle; and displaying on a display device the sighting reticle positioned on the graphical image to enable aiming at the target.
