This week we continue our compelling two-part program giving a powerful insight into one of the most controversial cases in Australian military history. At the centre of the story is Dave, a highly skilled commando in the Army Reserve. In February 2009, whilst on a capture-or-kill mission looking for Taliban, his unit raided a family compound in the middle of the night in Afghanistan. Six people, including five children, were killed. For the first time, Dave and other members of the unit give their account of the night and its aftermath. Dave and another soldier were subsequently charged with manslaughter of the five children and faced the possibility of a court martial and 20 years in prison. These charges were later dismissed. Since then, details of the operation have been shrouded in secrecy. What happened has been a tragedy for everyone - for Dave, his fellow commandos and, most of all, for the Afghan families who lost so much.
