Dog Section

The MDP has one of the largest Dog Sections of all British Police Forces. General Purpose (GP) Police Dogs and their handlers are deployed at 23 Dog Sections across the United Kingdom.  The GP teams are trained and licensed in accordance with the National Police Dog Assessment Model.  Selected teams will undertake further training to enable them to deploy in a tactical firearms support role alongside firearms officers.  The Force also operates several classifications of specialist search dogs which are deployed to search and indicate the presence of explosives and drugs, as well as firearms. All dog teams within the Force Dog Section undertake regular Refresher Course and Continuation Training which is delivered by accredited instructors.

Criminal Investigation Department (CID) and Fraud Squad

Our CID and Fraud Squad gather analyse and use intelligence to assess where the main threats to Ministry of Defence assets lie, and work closely with the MOD Defence Fraud Analysis Unit to combat crime.  The Fraud Squad is regarded as one of the foremost in the country; it has particular expertise in procurement type frauds and public sector corruption.  Officers are supported by civilian staff, including crime analysts and researchers.

Over the last few years, officers from the Fraud Squad have worked closely with the Serious Fraud Office on a number of cases.  The CID has a Computer Crime Unit and a Major Incident Unit, and work ranges from the recovery of stolen MOD assets to dealing with sexual offences.

Operational Support Unit (OSU)

The OSU is the MDP's mobile, flexible reserve.  OSU officers are able to be deployed at short notice anywhere in the UK in order to provide specialist policing skills.  These include protestor removal by use of cutting equipment and, where required, at height.

They can work in confined spaces as part of counter terrorism searches and they have a Level One public order and chemical, biological, radiological and nuclear (CBRN) capability.  The OSU is split into two sub units - OSU South based at HQ Wethersfield in Essex, and OSU North based at RAF Linton-on-Ouse.




Special Escort Group (SEG)

The Special Escort Group (SEG) provides protection for the safe and secure transportation of Defence Nuclear Materials throughout the United Kingdom. The SEG provides the staff for the Close Escort and Traffic Management of such Convoy Movements, working with Royal Marines and Atomic Weapons Establishment civilian staff.  Training on this group is intensive and it can take up to nine months to qualify.

Tactical Support Group (TSG)

Formed in December 2007, the AWE Division Tactical Support Group provides a dedicated specialist Firearms capability to AWE Aldermaston and AWE Burghfield.

TSG officers must be able to pass a rigorous selection procedure to achieve their high level tactical Dynamic Entry qualification.  Trained to the very highest national standard, these officer’s work and train in a demanding environment in order to fulfil their key role in protecting the nation’s nuclear assets.

Divisional Support Groups (DSG’s )

Divisional Support Groups are deployed regionally to support the complements in each MDP Division where extra resource is required for operations.

International Deployment

The MDP deploys the largest number of officers of any UK police force on secondments to organisations such as the United Nations (UN), European Union (EU) and other organisations involved in international peacekeeping missions.  This is normally in a post-conflict role where our past and present responsibilities have included training and mentoring a national police force, or monitoring and maintaining a stabilising international presence.  These tasks are performed in an environment where civil reconstruction work to restore an ordered community under the rule of law is being progressed.  MDP officers have consistently received the highest praise for their work in this field.
