Through his unique access to CO19, Smith has managed to put together hundreds of detailed photographs, both historical and contemporary, along with text that goes a long way to explain why it is necessary to have such an elite firearms unit on standby 24/7 in London. This comprehensive volume will bring you up-to date with the training, operations, equipment, and mindset of these courageous individuals who put their lives on the line on a daily basis to keep London safe.
