With regard to civil aviation security, laws and regulations apply that airports, airlines, handlers and all personnel, including security personnel, must abide by. The Royal Netherlands Marechaussee's Civil Aviation Security Brigade (Brigade Toezicht Beveiliging Burgerluchtvaart, BTBB) is responsible for monitoring compliance. For example, the brigade checks that security measures and security tasks are carried out properly. This is important for the millions of passengers and hundreds of thousands of tons of cargo that are flown around the world through Dutch airports each year. The supervision and compliance monitoring tasks of the BTTB are carried out on behalf of the National Coordinator for Security and Counterterrorism.
