more than likely a mockup for our pilots to practice target id
On the range there are huge complexes plowed out, airfields for example, with SAM sites, runways, aircraft in revetments, even railroad cars, etc. . .lots of fun to plan an attack and strafe and bomb.
I have many fun memories of doing just that when I was at D-M, checking out in the A-10.
Just a few targets:
Airfield: 32.71496, -112.600429
Airfield: 32.637677, -113.200029
Runway: 32.463065, -113.183013
SAM Site: 32.71496, -112.600429
Target: 32.690845, -113.296456
