Estremo onore

The word "Krait" which forms part of one of this movie's alternate titles, "Heroes of the Krait", refers to a a wooden hulled fishing boat known as the MV Krait. This vessel was used by Z Special Force in Operation Jaywick to plant bombs on Japanese ships at Singapore Harbour in September 1943 during World War II. The mission successfully sunk seven Japanese ships of war. The boat's original title prior to Allied ownership was "Kofuku Maru". She was renamed the "MV Krait" in 1942 by the Allied Forces when the vessel was handed over to the Australian Military. The boat was named after a Krait which is actually a type of snake. Many Australian Commando Unit vessels have since been named after snakes since the successful Operation Jaywick mission. This movie is based on two WW II Allied missions of which Operation Jaywick is one.

in the attack on the ships in Singapore harbor, mines are placed below the waterline, however the explosions come from the upper decks, when they should come below the water.
