Civil-military cooperation is permanent. It is particularly well demonstrated in the Vigipirate plan. Although Prefects are responsible for the general coordination of action in the fight against terrorism, the Armed Forces contribute very significantly and visibly in this, particularly inÎle-de-France where, at a request from the Prefect of Police/Defence Zone Prefect to the Military Governor of Paris, they intervene in support of the police and gendarmerie forces to protect the population.
