The British Ministry of Defence was censured by the Health and Safety Executive over the deaths of three soldiers who were trying to complete a grueling training exercise for selection into the Special Air Service back in 2013.

The men were on a 16-mile grueling march in the Brecon hills on Jul. 13, 2013 and one by one, their GPS trackers went static. By the time help arrived, one was already dead and another died at the hills in the evening. The last man died in hospital two weeks later. All had suffered hypothermia.
The HSE determined that the Ministry of Defense had failed to plan, assess, and manage risks associated with climatic illness during the selection exercise. The Ministry would had faced prosecution if not for crown immunity.
