If that was Colorado springs the answer may be alot more simple than many would expect.
Fort Carson is in that area, and they do live fire exercises, and back in the mountains there are several shooting ranges, almost kind of sounds like
something that you would hear from an army base doing live fire exercises. Use to hear them out on the plains east of Colorado Springs. Tanks,
Morters, and the occasional black powder rifle.
