They became employees of a new joint authority SFIRA/(insert preferred appeaser unionist party here) transitional authority. And of course there were one or two bad apples. Plenty of the British soldiers weren’t nullified or who didn’t commit suicide ended up in further criminal careers. Being uneducated UK cannon fodder they had few options really.After 'fighting' the state they became employees of it. Don't forget the ones that stayed in the narcotics business, illegal tobacco, became dissidents, and engaged in assorted criminal activities. Slab Murphy and the boys. Give a shout out to the ones in Maghaberry.
