A Royal Marine said he is "devastated" at being handed a life sentence for murdering an injured Afghan insurgent.
Sergeant Alexander Blackman said he was "very sorry" for his actions, which were filmed on the headcam of a comrade during the patrol in "the most dangerous square mile in Afghanistan".
Speaking after Blackman was led away to begin his sentence in a civilian prison, his solicitor Issy Hogg thanked the public for the support they have shown to him and his wife.
"He has been dismissed with disgrace from the Royal Marines, with whom he has served proudly for 15 years," said, adding that Blackman intends to appeal.
A Royal Marine jailed for life for the murder of an Afghan insurgent was told by the judge sentencing him he had disgraced the name of the British armed forces and put troops' lives at risk by his actions.
Judge Jeff Blackett told Sergeant Alexander Blackman: "This was not an action taken in the heat of battle or immediately after you had been engaged in a firefight.
"Nor were you under any immediate threat - the video footage shows that you were in complete control of yourself, standing around for several minutes and not apparently worried that you might be at risk of attack by other insurgents.
"You treated that Afghan man with contempt and murdered him in cold blood. By doing so you have betrayed your corps and all British service personnel who have served in Afghanistan, and you have tarnished their reputation."
Sergeant Alexander Blackman, 39, an experienced Royal Marine filmed executing an injured Taliban insurgent in cold blood, was jailed for life for murder by a court martial in Bulford, Wiltshire, today and told he will spend at least 10 years in prison.
A Royal Marine convicted of murdering an injured Afghan insurgent should be shown leniency due to the "exceptional circumstances" of the case, a court martial heard today.
Sergeant Alexander Blackman, 39, who has 15 years' experience in the Royal Marines, faces life imprisonment after executing the man in "cold blood" in Helmand Province in 2011.
But a judge and court martial board have been urged to pass the shortest sentence possible to give Blackman "a real anticipation of release".
The military court in Bulford, Wiltshire, is not due to deliver the sentence until this afternoon.
A Royal Marine convicted of murdering an injured insurgent in Afghanistan is to be sentenced this morning.
Sgt Alexander Blackman, whose names was made public yesterday by judges, faces a life term.
A Ministry of Defence spokesman has said:
The MoD acknowledges the lifting of the anonymity order in respect of Marine A.
We presented our security concerns in open court, and an independent legal process has now concluded; we respect the decision of the court.
Two Royal Marines who were acquitted by a court martial over the death of an Afghan insurgent should be named, judges have ruled.
However, their identities will not be released pending a possible move by their lawyers to take the issue on to the Supreme Court, the UK's highest court.
The shooting of an injured Afghan insurgent was filmed by a camera mounted on the helmet of Marine B.
Marines B and C were alleged to have been ''party to the killing'' and ''encouraged and assisted'' Marine A in committing the murder, but they were cleared.
The sentencing hearing in relation to Marine A, who has been named as Sergeant Alexander Blackman, is due to take place tomorrow.
A judge has ruled that the anonymity of the Royal Marine convicted of murdering a seriously injured Afghan insurgent can be lifted.
The commando, known as Marine A during the court martial, has been named as Sergeant Alexander Wayne Blackman.
Two other servicemen who were acquitted, known as Marines B and C, can also be named, the judges ruled.
