On the 7 July 2005 London bombings the UK was hit by directly by Islamist terrorism. Already before that incident the MDP had begun a programme of transformation of its uniformed assets known as 'enhanced capability'. This was a program of modernisation, re-equipping and training to concentrate on the new threats to UK national security and to perform the force's primary role: armed security and counter-terrorism. The acquisition of the Heckler &amp; Koch MP7 as the new force weapon came from this programme, because of the requirement to penetrate body armour.
