Map reading has always been and will continue to be a vital military skill. The ability to relate map to ground and vice versa is an essential skill for all ranks. Having determined his position and that of his objective, a soldier must be able to navigate between the two in the most expeditious manner. The advent of the Global Positioning System GPS has not diminished this requirement. Map reading and navigational skills are practical subjects that must be regularly practised and assessed if skills are to remain high.
