Other than a short stint on a patrol gunboat, most of my military
shipboard service was spent in helping track down and documenting the
locations of Soviet submarines with a new (at the time) system for doing so.

That was a major function of the ocean stations the Coast Guard ran
too. It was a pretty isolated group of guys doing it tho. The SONAR
gang lived and worked separately from the rest of us along with a
couple of civilians. That was the pre SOSUS days.
