Red bound version of the USMC Officer's Guide still included the story of a young Marine officer serving in the days of tall ships who was instructed by the Commandmant to demand satisfaction from the entire Navy Wardroom at the next port of call, or resign his commission as a coward. While that story struck a chord in me, I cannot imagine facing another man with a sword ... pistols maybe. So if FORCED to duel, I take pistols at 200 yds. Time those IHMSA dues paid off.
