A team of soldiers from the Army will be sent in to ease pressure on an ambulance service amid staff shortages due to COVID-19.
In all, 40 personnel will be available to Yorkshire Ambulance Service (YAS) NHS Trust, which has been struggling to transfer patients between hospitals.
The trust requested military aid to help fill gaps caused by staff who are off sick or self-isolating with the virus. YAS receives more than 2,500 routine and emergency calls each day.
YAS executive director of operations Nick Smith said: "We will be able to use military personnel to work alongside our staff, enabling us to support patients and get people the treatment they need sooner.
"They will receive YAS training in driving ambulances, manual handling, kit familiarisation and basic life support."
The military personnel will be working alongside staff at the trust for a number of weeks.
About 2,100 military personnel are already deployed across the UK supporting civil authorities in their response to the pandemic.
A week ago a team of about 150 military personnel joined forces with North West Ambulance Service (NWAS) to address staff shortages and increasing pressure due to COVID.
Government figures show there were 19,735 patients in hospital in the UK with COVID as of January 11, averaging 2,000 a day since Boxing Day.
