This is the shocking moment a squad of marines stormed a Plymouth-bound Brittany Ferries ship packed with holidaymakers.
Royal Marines from the 539 Assault Squadron and 42 Commando boarded the Armorique as she returned from Roscoff, approximately ten miles off the Devon coast.
Passengers watched on in shock from the upper decks as the commandos clambered up the rear of the ship at high-speed.
The exercise was designed to test the marines’ boarding skills, as well as their use of the Pacific 24 sea boats and climbing equipment.
The Royal Marines are one of only a few forces in the UK trained to conduct this sort of Operation, so it is vital we do this training regularly, under the most arduous conditions possible.
