evidence: The British Army's locally recruited Ulster Defence Regiment (UDR) was almost wholly Protestant.[233][234] Despite recruits being vetted, some loyalist militants managed to enlist, mainly to obtain weapons, training, and information.[235] A 1973 British Government document (uncovered in 2004), Subversion in the UDR, suggested that 5–15% of UDR soldiers then were members of loyalist paramilitaries.[235][236] The report said the UDR was the main source of weapons for those groups,[235] although by 1973, UDR weapons losses had dropped significantly, partly due to stricter controls.[235] In 1977, the Army investigated a UDR battalion based at Girdwood Barracks, Belfast. The investigation found that 70 soldiers had links to the UVF, that thirty soldiers had fraudulently diverted up to £47,000 to the UVF, and that UVF members socialised with soldiers in their mess. Following this, two UDR members were dismissed.[237] The investigation was halted after a senior officer claimed it was harming morale.[237] By 1990, at least 197 UDR soldiers had been convicted of loyalist terrorist offences and other serious crimes, including 19 convicted of murder.[238] This was only a small fraction of those who served in the UDR, but the proportion was higher than the regular British Army, the RUC, and the civilian population.[239]
