A World War Two Willys Jeep was driven through a dip tank to simulate a vehicle getting off a landing craft into the water. The tank, which has a fording depth of up to 1.5m, tests the waterproof capability of vehicles.
At a special themed event to mark the 75th Anniversary of D-Day in North Devon, Royal Marines from Instow put several World War Two vehicles through their paces, including this Willys, alongside their modern-day equivalents.
As part of 1 Assault Squadron RM, the small dedicated 11 Amphibious Trials and Training Squadron at RM Instow is responsible for developing new equipment that will meet the Royal Marines amphibious and surface manoeuvre needs.
The unit is unique as it is the only one in the MOD that carries out the development of specialised equipment and training in this field.
First established during World War Two, the base was initially used as a training facility for troops preparing for the Normandy Landings at Arromanches and Gold Beach in June 1944.
It is now active in developing new technology and ways to deliver equipment, vehicles and troops to landing beaches across the world as well as looking at landing vessels for commando forces of the future.
