Not sure where but it is interesting

 

 

Mmmm, why is only one painted up in desert colours? The other 3 been rushed into service?

Good question and some of them are running the old style tires too.

All seem to have the older radar reflector/designator panel's too which were used before Carc 2 came out.

All are running aux infrared lights and the building has several roof top AC units.

Just kinda strange with the back drop of a semi modern fortress.

I hadn't missed the building, but I think it's all modern.

yup, but I don't know whats under the thing and was giving the hill credit for a possible older site.

Possibly, many sites retain their strategic importance throughout the ages.
