We had a remote Nike Hercules battery about 5 miles from our motor pool. When they had a Nuclear Surety Inspection, we were called out to provide a support team of 40 soldiers, and two towed Vulcans.
It was serious, we issued live ammunition and loaded the Vulcans to the breech with 20mm rounds. In the four hours we had to make our mission time, I took at least two for infantry refresher training (we were ADA).
Fortunately, we never had any injuries or saw a round fired accidentally. There were always observers from the nearest town, I had no doubt a few Gang members were there, too.
What was your ROE on that mission?
