The Defence Police College (DPC) at Southwick Park, near Cosham, England, is a tri-service establishment for training the Service Police of the British Armed Forces (Royal Navy Police, Royal Marines Police, Royal Military Police, and Royal Air Force Police). It replaces Service Police training establishments at HMS Excellent, RMPTS Chichester and RAF Halton. The site is owned by Defence Estates and is flagship-leased, which means that permission has to be asked by the Service Police to use the parade ground.
