The Armed Forces are supporting local police as world leaders arrive in Cornwall for the three-day G7 Leaders' Summit in Carbis Bay.
Defence is providing a range of capabilities including naval vessels, aircraft, planning staff, logistics support, facilities and Explosive Ordnance Disposal teams.
At the request of Devon and Cornwall Police, the Armed Forces are providing explosives search dogs and handlers who will be under police command.
UK defence is also providing facilities to support the delivery of the summit, including RNAS Culdrose and RAF St Mawgan, while also providing air defence capabilities and a Type 23 frigate, HMS Northumberland, two Offshore Patrol Vessels including HMS Tamar and six Archer class P2000 patrol vessels.
Commodore Rob Pedre, Commander of the Littoral Strike Group, is co-ordinating the military's contribution and said: "We are proud to be involved in this monumental event, and to help enable a global forum where leading democracies will tackle the biggest issues facing the world today."
Hundreds of Armed Forces personnel are supporting the police in a variety of roles, including as drivers and wider logistical support.
Personnel drafted in to help are freeing up police resources for other frontline roles.
In total, there are more than 5,000 police officers plus military personnel from all three services deployed.
Inspector Alex Stypulkowski of the Ministry of Defence (MOD) Police Marine Unit told Forces News he is "privileged and proud" to be supporting the logistics and un-armed operation of the police response, ensuring officers are ready, equipped and trained for their duties.
"The MOD Police logistics team have been heavily involved in the planning of the maritime operation, involving not just our own assets but those belonging to our Home Office force colleagues," he said.
"We've also got officers involved in the logistics, making stuff happen on the ground, with the vessels, vehicles and equipment being moved where they need to be, and another planning team involved in making that happen."

Some military personnel involved with the event will also perform ceremonial duties to mark the summit including a Guard of Honour for delegates.
Devon and Cornwall Police's Superintendent Jo Hall said: "Throughout our planning of the security operation for the G7 Leaders' Summit, colleagues from the military, who are well versed in logistical planning, have been embedded within our team to provide essential knowledge and assistance.
"We're glad to be joined by mutual aid officers and staff from all UK police forces and the armed services, who will be supporting the delivery of a safe and secure event."
Mutual Aid arrangements have allowed officers from across all police forces in England, Wales and Police Scotland to be drafted in to assist Devon and Cornwall officers.
The G7 – Group of Seven – is an organisation made up of the world's seven largest advanced economies. They are Canada, France, Germany, Italy, Japan, the UK and the United States.
The summit begins on Friday and finishes on Sunday.
