What describes the prescribed course to be traveled from a point of origin to a destination?

The term that describes the prescribed course to be traveled from a point of origin to a destination is "route." In military terminology, a route is a defined path that units follow for movement or transportation. It includes specific roads, trails, or avenues of approach that are necessary for ensuring that forces arrive at their intended destination efficiently and securely.

Routes are essential for planning movements and operations, as they help to minimize risks and maximize operational effectiveness. By designating a route, commanders can account for variables such as terrain, enemy presence, and logistical considerations, ensuring that movements are conducted in a coordinated manner.

While "path," "course," and "track" can also imply a direction or way of moving, they do not carry the same specific connotation of an established or designated route as used in military operations. A path may simply denote a way or track without the same authoritative context, a course may refer more broadly to direction or a route in terms of navigation, and a track is often used to refer to the physical marks left by movement rather than the planned movement itself. Thus, route remains the most appropriate term for prescribing the course of travel from point A to point B in a military context.
