An ex-soldier who repeatedly stabbed a former loyalist gun runner to death has been jailed for seven years.
Lindsay Robb was attacked in a Glasgow street on Hogmanay
Brian Tollett, 29, from Glasgow, was found guilty of culpable homicide after he killed Lindsay Robb, 39.
Mr Robb's family shouted out in anger at the High Court in Glasgow at the length of the sentence and described Tollet as "pure scum".
The court was told Tollett was suffering from post-traumatic stress after serving in the Balkans.
He stabbed Mr Robb 22 times.
Sentencing, Judge Lord Brailsford said he had taken into account the killer's psychological problems as a result of his service.
He said: "These problems were caused by your service for Queen and country in the Balkans.
"It is clear from the report that in the course of your military service which is to be praised, you experienced unpleasant things in the form of mass graves which we have heard about in the news and witnessed a land mine which caused the deaths of your colleagues."
Mr Robb, a one-time loyalist commander, died following a struggle on 31 December last year.
The court heard Tollett, a former member of the Royal Fusiliers, got into a fight with him over a £140 drug debt.
The attack was witnessed by passers-by, including a 10-year-old boy, on Gartloch Road in the city's Ruchazie area.
Lord Brailsford said it was not unprovoked and that the fatal blow was inflicted as part of a "mutual struggle".
Robb settled in Lanarkshire after being released from prison in Northern Ireland in 1999 under the terms of the Good Friday Agreement.
He was convicted four years earlier for his part in a loyalist gun-running operation.
