I was (wireless) radioman in a Mountain Infantry Unit in the Swiss Army (1957to1999), Batt.43/I. In my Unit we also used a secret code system for the different stations, places and terms. My name was "Lighthouse" (because I'm tall), and a second "DeGaulle". We had previeved this for occasions when our normal net was broken, and this was the case in a verry big trouble in the Big Manouvers (the Swiss Army was not really involved in real wars). I was choised because I know a fiew linguages, my "Second" spoke German and French.
We had a verry interresting time. I still have a orig.
ENIGMA cipher machine.
