A collision course, also known as a kamikaze run, is the deliberate maneuver by the operator of a moving object to collide with another object. It is a desperate maneuver since it often damages or destroys both.
Uses in history

Kamikaze pilots from Japan used collision course tactics to take out naval vessels or large Bombers in the latter days of World War II. Such tactics even extended to the construction of dedicated kamikaze aircraft, such as the Ohka.
