The “crop circle” in Nevada is actually a SAM-site. That is, a prepared base for Surface-to-Air-Missiles.
Or, a training site for aircraft to attack missile sites. Nevada desert is very good for this type of training.
(The base is empty on the picture, but ready to be occupied. The radar and optronics goes in the center, and the missile batteries are spread out around it. The different parts protected by sand berms. If one of them should be hit by an aircraft attack, the others may survive the blast and shrapnel.)
