WE don’;t have our OWN POWER SOURCE??? OMG!!
I have not been to Turkey, but I’ve been on numerous DOD installations over the last 40 years, including recent visits to joint-use NATO and other foreign bases. The US military at these locations has always had backup generator capacity for emergencies. So communications and emergency lighting, etc, will be available.
They are operating on generators and have emergency water supplies. At some point generators run out of fuel
