Q: Question: What is the population of the city that was seized by the Royal Jordanian Army's 17th Armoured Brigade in the southern part of Jordan? Passage:The Palestinian-dominated Royal Jordanian Army's 17th Armoured Brigade has revolted with Syrian assistance, and has seized the southern part of Jordan, including the port city of Aqaba. However, the major concern for the British Army is that a prototype main battle tank on trials in the Jordanian desert has gone missing. After a terrorist attack in London fails, British military intelligence discovers that the tank is hidden in the ruins of an ancient Crusader fort near Wadi Rum. SAS-trained Major Harry Maxim, who formerly trained the Jordanian Army, is the ideal candidate to send in a commando raid to destroy the tank before it can fall into rebel (and thus Soviet) hands. However, the mission is botched when Maxim's helicopter crashes, and Maxim, an infantryman with no Armoured experience, decides that the best chance for the survival of his small team is to attempt to drive the tank across a hundred miles of rebel held desert to the presumed safety of Saudi Arabia.
