Royal Marine wore sergeant's uniform to wedding while still a corporal
A Royal Marine who dressed in a sergeant's uniform while still a corporal has been fined £300.
Robert Barnett, of 40 Commando, admitted wearing the uniform - plus medals he was not entitled to - at a family wedding last June.
He had denied conduct prejudicial to good order, saying he wore them at a private event, not on duty.
Barnett, who has since been promoted to sergeant, was found guilty at a court martial in Portsmouth.
'Big it up'
Capt Benjamin Taylor, prosecuting, told the court martial that Barnett, 33, who is based at HMS Raleigh in Plymouth, had been an acting sergeant in 2011, but was a corporal again in June 2012.
He has been in the marines for 16 years and seen service in Iraq, Afghanistan and Kosovo.
His offence came to light when other marines saw images of Barnett at the wedding in Harrow, North London, on Facebook, the court heard.
As well as the uniform, the pictures also showed him wearing a Long Service and Good Conduct medal, a Nato medal for operations in Afghanistan and the King's Badge - awarded to the best recruit of any batch to pass out from training - none of which he was entitled to.
Capt Taylor said by wearing the items Barnett had "fundamentally undermined good order and discipline and showed complete disregard to them" and "he did it to show off and impress others".
Regimental Sergeant Major Joseph Gillespie said in a statement that he talked to Barnett about it.
"He [Barnett] replied he wanted to look good in front of his family. He wanted to 'big it up' in front of his family," he said.
Barnett denied the conversation and said the medals were a gift from his father and he used them as his real ones had been sent away to have the Diamond Jubilee Medal added.
"I knew I was not a sergeant. It was a private wedding and I never thought the photos would see the light of day," he told the court.
The court martial panel of three Royal Navy officers also heard he meant no disrespect to the service.
The offence carries a maximum sentence of two years imprisonment.
