A British Army soldier who sexually assaulted a teenager has been thrown out of the military.

Signaller Ryan Pell 'overpowered' his much smaller victim, subjecting her to a 'never ending' ordeal and repeatedly trying to kiss her during a late-night walk at Blandford Camp in Dorset.

The 26-year-old also drunkenly pinned the girl against a fence, pushed her onto the floor and straddled her.

After a trial at Bulford Military Court, Pell was found guilty of three counts of sexual assault.

Dismissing him from the army, Britain's only female military judge told the soldier he only had himself to blame for “destroying his career”.

Assistant Judge Advocate General Jane England told Sig Pell: “She was telling you to get off, but you were saying it is a bit of fun. It was not fun.

“When she went on that walk, she had no reason to fear you. You are much larger and stronger than her and you have the build to overpower her, which you did.

“You did not want to take no for an answer.

“It is always unfortunate when someone of your position does something to destroy their career, but the only person to blame for that is you.”

She dismissed Sig Pell from the armed forces, handed him a 24-month suspended sentence and ordered him to pay his victim £1,000.

His victim told the court that she has suffered sleeping problems since the incident and is now alarmed when a man raises his voice at her.

In a statement, she said she has struggled to sleep and suffers flashbacks of the incident.

“In the weeks leading up to the (trial), I would not sleep at all,” she said.

“Before the incident, a male raising his voice at me would have not bothered me, but this has definitely changed since the incident.”

James Ross, defending, said Sig Pell was the “author of his own misfortune” and had it not been for that one night, he would have “contributed a great deal to the armed forces”.

Judge England told the soldier: “You have shown no remorse or acceptance of responsibility for your behaviour.”
