What is not one of the five general methods to describe direction to a gunner?

The method of Vector Analysis is not considered one of the five general methods to describe direction to a gunner. Instead, the five general methods typically include concepts that are more intuitive or universally applicable in directing fire.

Methods such as using a reference point involve specifying a landmark or another identifiable object to guide the gunner. The clock method utilizes the analogy of a clock face to indicate direction, making it easy to visualize angles and positions relative to a standard reference. The term traverse refers to movement in a horizontal direction, which is crucial when adjusting the aim or fire direction.

While vector analysis is a useful mathematical tool in many fields, including physics and engineering, it doesn't fit within the conventional methods employed on the ground for directing artillery, as it's more complex and not always necessary in operational contexts. The focus in military training is often on more straightforward, practical methods that can be quickly communicated and understood in the field, which is why vector analysis does not belong to this particular set of methods.
