Can you explain to me the workings of the phrasal verb “vector in” in the sentence “The insurgents are already vectoring in from the east”?

I think I sorta understood the meaning of it (or maybe I didn’t), but I’d still rather a clear definition.

This sentence is composed by the very first words in the short story The Colonel, in case some more context is needed.

Thank you for taking the time to read my request.

Answer

In mathematics a vector is a line having both direction and distance, but in aeronautics it is used to identify the course, or series of courses, that an airplane should follow to reach a point, often an airport. To “vector in” is to follow directions describing a route (which may consist of multiple changes of direction) to a destination.
