Sojouner,
glad my (normal) high handed manner didn't upset you! Mea culpa.
To answer your question, no not a marine. You would know it in your forces as electronic weapons officer, although my job title was (before retirement) weapons systems officer. Just as a little light relief, I was once seconded to a ship as part of my duties, not bad for a fly boy eh? At least the navy boys thought so, as my first week was spent looking a peculiar green colour.
