The avatar is part of an insignia on the battalion crest of my last air defense unit. The insignia has a ship because the battalion began as "Coastal Artillery Corps" and evolved to become an air defense unit operating the Nike-Hercules Missiles equipped with nuclear warheads. The Fleur-de-lis is from the artillery battalion being posted to France during WWI. The ship represents an enemy target of the old coastal defense batteries. This battalion was my last and most pleasant posting as these missile sites throughout the USA were completely dismantled by 1975. Nothing took their place.There is no missile defense to save you. We're all on your own. Good Luck.
