On several occasions, a man claiming to be the soldier’s commander rang her to reassure her he was about to fly to Britain.
Gemmell, 29, was jailed for 20 months and placed on the Sex Offenders Register for ten years and faces being discharged from the army in disgrace.
A number of computer items were taken away for analysis and Gemmell subsequently admitted messaging the boy before meeting him for sex.
The court was told that the soldier had met the boy on a single occasion shortly before Christmas and had been arrested a short time later.
He asked for at least £20,000 from her to buy official military ‘leave passes’.
He claimed he was unable to take leave and could only get it by using fake documents he needed to pay for.
