Dermot Rooney

Dermot Rooney is a military psychologist and defence analyst who has spent 30 years working for the British Army, Ministry of Defence and NATO. He has interviewed hundreds of veterans, spent months embedded with units to analyse how they work, and spent years poking through dusty archives. He was once tricked into becoming a paratrooper so he could “understand fear”. Slog or Swan is based on Dermot’s PhD thesis, which was awarded the Andre Corvisier Prize by the International Commission for Military History. His previous works include Brains & Bullets: How Psychology Wins Wars.
