In the nine-part report series Bij de Marine, we follow the hardships of a marine training class. Who among them is strong enough to make it to the finish? We also go aboard the frigate Hr. Ms. van Amstel, whose crew undergoes an intensive training programme in preparation for participation in the permanent international NATO force in the Mediterranean Sea. We also visit places normally inaccessible to the general public, including a Lynx helicopter, an Orion aircraft, a submarine and a minesweeper, giving viewers a realistic and human picture of the Navy as an organisation.
