I had to do a job where the dock wasn’t stable, and they couldn’t unload a nuclear submarine of its missiles. So there it sat on the water (under a roof).
They told me not to cross the yellow line that was a foot or so from the sub. The four guys standing on the sub with their rifles seemed ready all the time.
Two small boats with what looked like .50 caliber guns swept back and forth both fore and aft of the sub.
I figured everybody was ready to go. Not that I was going to test them or anything!
Since 911 maybe sooner I’m sure the rules of engagement changed and rightly so. The 1974 rules are probably a lot different than now. I didn’t carry back then. I damn sure do now, and I don’t have to rack in a round. You ain’t carrying you lose, it ain’t loaded you lose. Losing is not an option.
