The tank used in the movie, "Reign of Fire", what was it it? This was a movie about dragons being awakened in modern times and they for all intents and puposes destroy the world. Anyway there is a tank used in the movie and based on the tip of the barrel, the side skrt, and the country it was in (England), it appeared to be either a Chieftain or a one of the Challengers. I would say Chieftain but the little odd shaped potrusion atop the very tip of the barrel is a characteristic I have only seen of both the Challengers and the Kahlid [an upgraded Chieftain used in the Jordainian army] in all the reference material I can did up namely the Illustrated Directory of Tanks of the World. Any help would be appreciated i'd like to model this subject.
