The Ulster Volunteer Force (UVF) is an Ulster loyalist paramilitary group originating in Northern Ireland. Their main goal is to combat Irish republican paramilitary groups and to keep Northern Ireland in the United Kingdom. They appear to also be a for-hire group, capable of carrying out tasks for the right price; including murder.
Red Right Hand
The Red Right Hand are well-trained members of the Ulster Volunteer Force. In June 1922, Chief Inspector Campbell hired the Red Right Hand in an attempt to execute Thomas Shelby. However, after Thomas was brought to an abandoned field for execution, one of the members intervened by shooting the other two, sparing Thomas in the process. He announced that Winston Churchill had work for Thomas and let him go away.
