Which method is NOT included in target location methods?

The choice regarding "Estimation by aerial reconnaissance" is not included in the standard target location methods primarily because it lacks the precision and accuracy necessary for effective targeting in modern military operations. Target location methods typically require exact techniques or technologies that enable the identification of targets with high reliability.

The other methods listed, such as grid coordinates using precision imagery, laser grid, and shift from a known point, are established practices that utilize specific technologies and established procedures to ascertain target positions accurately.

Grid coordinates using precision imagery provide exact positions based on satellite or aerial imagery, ensuring a reliable reference for targeting. The laser grid method utilizes laser rangefinders to determine distances and coordinates with precision, ideal for situational awareness and targeting. Shift from a known point allows for adjustments in targeting based on previously established reference points, enhancing accuracy in dynamic environments.

In contrast, estimation by aerial reconnaissance relies on visual observation and subjective evaluation, which can lead to inaccuracies due to weather conditions, visibility issues, or human error. This method is more prone to variability and lacks the systematic approach required for effective target acquisition in fire support operations. Therefore, it does not align with the rigorous standards of modern target location methods.
