The MDP has a large marine fleet whose main task is to ensure the protection of HM Naval Bases by providing armed security and patrolling the waterfront.
The units also escort Royal Navy submarines and surface vessels, and those of visiting navies, to and from the sea. Officers in the marine units are required to train to Royal Yacht Association standards; this can range from Competent Crew to Coastal Skipper.
The MDP currently has the second largest dog holding of any Police Force in the UK. Police Officers selected as dog handlers work within a specialist role that requires their team to be trained to operate in a diverse range of deployments. All dog teams are trained and licensed in accordance with ACPO and Police Scotland standards commensurate with the role performed. This ranges from the General Purpose Police Dog to the Tactical Firearms Support Dog in support of firearms operations. It also encompasses specialist search dogs that can indicate the presence of elements such as explosives and drugs. All dog teams in the MDP undergo regular refresher training and are assessed to ensure they remain operationally compliant.
