Nearly 200 Armed Forces personnel from the COVID Support Force are being mobilised to support ambulance services across the country.
In response to the coronavirus outbreak, members of the British Army, the Royal Air Force and the Royal Navy will support NHS ambulance services as they face increased pressure.
"Our Armed Forces always step forward at the appearance of threats to the country and its people," Defence Secretary Ben Wallace said.
"Across the United Kingdom, soldiers, sailors, airmen and women have got the backs of our NHS colleagues as they confront coronavirus."
Many of the people the Ministry of Defence is mobilising are civilian emergency responders in their off-duty time.
They will be wearing NHS uniforms as they assist in a variety of roles such as driving emergency response vehicles, taking calls from the public, working in response centres or as support frontline paramedics.
Ten Critical Care Transfer teams consisting of 21 Armed Forces medical personnel will support the London Ambulance Service moving critically ill patients between intensive care units when required.
A small number of engineers from the British Army’s Corps of Royal Electrical and Mechanical Engineers (REME) have also been working with the London Ambulance Service to maintain suction units used to care for patients in ambulances.
Eighty personnel have been mobilised to support the South Central Ambulance Service's frontline response to COVID-19 in Berkshire, Buckinghamshire, Hampshire, Sussex and Surrey.
They will man emergency response vehicles, drive ambulances and support emergency response centres in taking calls.
Sixty members of the British Army have been assigned to support the Welsh Ambulance Service NHS Trust's frontline response to the virus, assisting paramedics with non-clinical tasks.
Support to the Scottish Ambulance Service is coming from RAF Puma helicopters at Kinloss.
The Puma crews worked with the Scottish Ambulance Service, the Emergency Medical Retrieval Service and NHS Scotland to trial the loading of the EpiShuttle, a system that will allow patients to be transported safely to emergency care facilities, onto a Puma helicopter.
A further 37 military personnel have been deployed to assist the East England Ambulance Service (EEAS) in Bedfordshire, Hertfordshire, Essex, Norfolk, Suffolk and Cambridgeshire.
All those deployed to assist the EEAS already volunteer as emergency responders and have completed training with the East England Ambulance Service.
Their roles will include driving vehicles, assisting dispatchers in Emergency Operations Rooms and with logistics or administration in the EEAS Resource Centre.
