Footage of the Royal Marines carrying out exercises on the Thames around Tower Bridge on October 23 in preparation for a demonstration tomorrow.
In the footage, high-speed RIBs were seen speeding up and down the Thames and circling a passenger ferry.
Tomorrow, the Marines commandos will launch a high-speed “simulated assault” on the Thames with their Dutch counterparts as part of the Netherlands state visit to London by King Willem-Alexander and Queen Máxima.
