Saudi Arabia’s rulers capped a large military exercise on Tuesday by publicly parading their ballistic missiles for the first time. The King of Bahrain, the Crown Prince of Abu Dhabi, Kuwait’s Defense Minister and the Pakistani Chief of Army Staff were also in attendance, according to Jane’s Defense Weekly.

The Saudis haven’t disclosed how many of the DF-3 missiles they have, but Jane’s reports that the number is believed to be between 30 and 120.
