Two soldiers from the 11 UDR 's C Company ( also UVF members ) were convicted of the 1975 killing of three musicians from The Miami Showband . This attack was led by Robin Jackson , a former UDR soldier who had been discharged for " undisclosed reasons " . Two soldiers from 11 UDR 's E Company , Portadown ( also UVF members ) , died in the premature explosion of their own bomb . In 1977 , the Army investigated D and G companies of 10 UDR based at Girdwood Barracks , Belfast . The investigation concluded that 70 soldiers had " links " to the UVF . Following this two were dismissed on security grounds . 30 NCOs from D Company were suspected of fraudulently " siphoning off " between £ 30,000 - £ 47,000 . A large percentage of this was suspected of going to the UVF . It was also alleged that UVF members socialized with soldiers in their mess . The investigation was halted after a senior UDR officer claimed it was harming morale . Details of the investigation were discovered in 2011
