Stand your ground and assess the enemy, numbers and weapons used.
Fight the enemy using what you carry on you and what is in your immediate surroundings, whilst rallying other patriots to your hue and cry.
Protect the British public and support and defend those that stand with you. Neutralise the enemy and restrain them under your arrest. If you are not physically restraining a Wahhabi terrorist then offer help to any victims of their cowardly actions.
