What is the difference between afterglow and vectors?

Afterglow and vectors serve different time horizons on the radar display. Afterglow is the fading trail that shows where the target has recently been, giving you a visual history of its movements. Vectors, on the other hand, indicate the projected path the target would take if it keeps its present course and speed, providing a forward-looking forecast from the current position. This distinction is why the correct statement says afterglow shows past positions while vectors show future motion.
