In England, Damerment volunteered to work with the Special Operations Executive and was allocated the cover name Martine Dussautoy and commissioned as an ensign in the FANY. Sent to Scotland for paramilitary training, Captain Dixon-Robertson, her signals instructor at Inverie (STS 24), determined that, only being considered fair for sending and receiving messages, she was unsuitable for work as a wireless operator , though Captain Smith reported that for physical training Damerment was a "keen and hard worker with good stamina." Damerment had a good grasp of the principles of close combat, worked well and was aggressive. For rope work, she was reported to have fair muscular strength and good co-ordination but required more practice. She worked well and showed keenness in fieldcraft although she found the theoretical side difficult.
