Organised by the SAS, the training teaches key survival skills such as noticing anything unusual in your surroundings, driving under pressure and passing on coded messages. It is routine for royals, other VIPs and people working in dangerous countries.
William took the course aged 16, and was taught how to handle a submachine gun and was bundled into a car in a mock ambush.
And this type of training may have been behind Princess Anne's quick thinking when she foiled a kidnap attempt in 1974.
She was praised for her bravery in staying cool when her car was ambushed by an armed man suffering from mental illness.

Over 30 years later, the newest member of the family is being schoolled in how to handle all eventualities.
