For clarification's sake: I'm a civilian contract employee working out of Bagram, Afghanistan. The range in question is the SOF (Special Operations Forces) practice range, which is about 100 yards away from my CHU, or Containerized Housing Unit (read: shipping container with AC and furniture.) They usually shoot larger caliber weapons so, while my headphones do cut the sound down a bit, I'm just too close to cut it entirely. Saying it "opened" was a bit off... it DID RE-open recently after being out of commission for months due to fire, so I'd gotten used to the jets, helos, drones, and occasional rocket w/o the gunfire. Overall, it isn't bad until you get a couple of jerks firing heavy calibers rapid fire. That tends to sound like an insurgent attack, which one does not want to sleep through.
