Armed Response tells the gripping and often alarming story of SO19, the Armed Response Unit of the Met, and the Trojans within SO19 - the armed response vehicles permanently on patrol. Driven by the need for experience armed officers to be on the scene within minutes, the men and women of SO19 are called upon to stare death in the face as a matter of routine. This fully revised and updated edition, including a new chapter on the London terrorist attacks and their aftermath, provides a vivid and extraordinary account of the work these brave men and women undertake.
