Dockyard coppers have been around for a long time - but who are they? What do they do? Why do we need them? And are they even 'real' police? Roy Haines should know. He was one of them for thirty-eight years. As part of the national force called the Ministry of Defence Police - or 'MOD Plods' as they are more generally known - they patrol naval bases from Plymouth to the Clyde, and dozens of other vital defence sites throughout the UK. Roy joined the force in 1971, the year of its inception, and over the last five decades, he's seen the MOD Plods adapt to the changing face of terrorism, civil unrest and political upheaval. Join Roy as he guides you through a very personal account of a long and eventful career, based at Portsmouth and Chatham dockyards with occasional diversions to the West Country and London. Like every long-serving police officer, Roy experienced his fair share of tragedy, fear and courage ... not to mention the outright bizarre!
