More than 200 UK servicemen and women are deploying to support the Scottish Ambulance Service dealing with the pressures caused by COVID-19.
A total of 225 personnel will be tasked starting from this Saturday – 114 of those driving ambulances.
The other 111 will begin operating mobile testing sites from next Wednesday and will include soldiers from 2 SCOTS.
Watch: Personnel in Scotland have also been tasked with giving vaccinations during the pandemic.
They are both roles the British military has helped carry out since the start of the coronavirus pandemic.
The tasking is likely to last for several months, with their support focusing on the Arran, Ayrshire, Edinburgh, Fife, Glasgow and Lanarkshire areas of Scotland.
Scotland's First Minister Nicola Sturgeon asked for the Armed Forces' assistance last week.
Defence Secretary Ben Wallace said: "We are proud to work alongside the dedicated men and women at the Scottish Ambulance Service as they continue to provide a lifesaving service to the people of Scotland.
"Our commitment to provide rapid support to communities and civil authorities is being delivered alongside the deployment of thousands of personnel on operations around the world."
Scottish Secretary Alister Jack said he was "grateful" for the military's work in response to COVID-19.
