The medals may be what you say, Gil, but the ATS uniform was normally used as a "cover" for female SOE agents, meaning that the ladies weren't actually doing what was normally associated with ATS personnel, they were secret agents.
SOE operated across occupied Europe.
My understanding is that SOE agents normally "worked" in the SOE section that they were assigned to. For example, SOE agents "working" in the Norwegiansection would normally expect to work in Norway unless a specific operation demanded that they cross into another country. A SOE agent wouldn't routinely expect to be sent to another country other than the country of the section that they were working for, in my opinion. An SOE agent working in the French section would normally expect to be sent to France but there could be operational reasons why they may have been sent to other countries, on occasions. I would expect a SOE agent routinely working in North Africa to be a member of the North African section, not the French section.
The "Finishing School" for SOE agents was on the Beaulieu estate, now home to the UK's National Motor Museum.
