Nicola Sturgeon has said Scotland is "very grateful" for the military's logistics support during the rollout of a coronavirus vaccine.
The First Minister of Scotland said military planners are working with the Scottish government as plans to distribute vaccines north of the border are being finalised.
It comes after the UK became the first country in the world to approve the Pfizer/BioNTech COVID-19 vaccine.
Ms Sturgeon said: "We have, obviously, NHS boards very centrally involved in that planning process [and] local authorities are also involved in helping us identify sites and some of the other logistics.
"We have assistance from the military right now in terms of the logistical planning around all this, for which we are very grateful indeed."
Ms Sturgeon added the effort to distribute a vaccine will be the biggest peacetime logistical challenge the country will ever have undertaken, describing it as "a massive, massive operation".
The Scottish government is looking to establish large facilities across the country to immunise as many people as possible.
The first vaccines are to be handed out next week to those at most risk to the virus before being rolled out wider early next year.
