This image shows a conceptual Nike-X deployment. On the left is a Sprint base with a MAR in front of it. Not the double-pyramid shape of the MAR, which evolved after the experimental MAR-I in White Sands was built in a dome-like building. In the background is a second base with more Sprints and its own radar. Normally one of these would use a MSR instead of MAR, but in this image it appears both site use the MAR.
