Our lecture in 2017 about Artificial Intelligence generated much interest and discussion. Amongst the issues raised was the whole question of remotely controlled or even autonomous weapons. We are delighted to welcome two retired senior officers to help us explore this further. Lt Gen Sir Robert Fry KCB RM is a former commandant of the Royal Marines and served as coalition deputy commanding General in Iraq in 2006 before retiring to head Hewlett Packard's Enterprise Services, Defence & Security UK. Air Marshal Sir Christopher Coville KCB was Deputy CinC Allied Forces Northern Europe and Air Member for Personnel before his retirement following which he served as the chairman of Augusta Westland.
