The Royal Marines were originally formed under the auspices of the Royal Navy to guard its sailing ships from harm. They are proud of their history and origins but the Navy heritage is fading. John Parker charts how the units have moved away from their nautical beginnings to develop, over time, into the most versatile force in the British military, containing one of their most elite brigades.

The Royal Marines Commandos have, over the past few years, developed into the premier fighting organisation on land, sea and air. This history deals with events associated with the Royal Marines and subsequently in their commando role, starring in all major conflicts including Italy, Malaysia, the Borneo confrontation with Indonesia, and more recently Afghanistan.
