The Sands of Ammon (original title: Le Sabbie di Amon) is the second part of Valerio Massimo Manfredi's Alexander trilogy, following on from "Child of a Dream".
 Continuing the epic story of Alexander the Great, "The Sands of Ammon" narrates of the Macedonian king's quest to conquer Asia.
 He and his men storm and conquer Persian towns and harbours; even the legendary town of Halicarnassus is defeated.
 Alexander's army marches on to the snow-covered Anatolia, where it records yet another few victories.
 Despite defeating the king Darius III, the city of Tyre and the Towers of Gaza prove to be formidable enemies, although they ultimately have to surrender to Alexander.
 The Macedonian army then heads south towards the mysterious and epic land of Egypt; and it's here, in the sands of the endless Libyan Desert, that the Oracle of Ammon lies.
 And what the divine Oracle will reveal to Alexander will change his life forever.

 The lineup for "Thrust" is the same as on "Head Hunters", except Mike Clark replaced Harvey Mason on drums.
 This is Hancock's thirteenth album overall.
Market hunters, or commercial hunters, hunt wild land animals.
 (Their counterparts at sea are called commercial fishermen and whalers.)
 They are distinguished from subsistence hunters and recreational hunters by their use of the animals they kill: Market hunters sell or trade the flesh, bones, and/or skins and feathers of slain animals as a source of income; subsistence hunters and their families and local tribes use these materials directly as food, clothing, tools, and/or shelter; recreational hunters often consume the flesh of their kills and/or use the skins for decoration or clothing.
The Emperor's Naked Army Marches On (ゆきゆきて、神軍 , Yuki Yukite Shingun ) is a 1987 Japanese war documentary film by director Kazuo Hara, whose title is loosely based on the classical tale The Emperor's New Clothes.
 The documentary centers on Kenzo Okuzaki, a 62-year-old veteran of Japan's campaign in New Guinea in the Second World War, and follows him around as he searches out those responsible for the unexplained deaths of two soldiers in his old unit.
In the Land of the Head Hunters (also called In the Land of the War Canoes) is a 1914 silent film fictionalizing the world of the Kwakwaka'wakw peoples of the Queen Charlotte Strait region of the Central Coast of British Columbia, Canada, written and directed by Edward S. Curtis and acted entirely by Kwakwaka'wakw native people.
The Commemorative Medals for Army Marches are two distinct medals awarded for participating in the two marches organised yearly by the Belgian Army.
 They are not decorations, but they may be worn by members of the Belgian Armed Forces on their uniform during the year following the participation if they request it.
 For members of the Belgian Army, participating in the marches counts as operational training.
