AGA is an acronym for the Ancient and Honorable Artillery Company of Massachusetts, which is the oldest chartered military organization in North America. SIR is a title of honor used in the United Kingdom and other Commonwealth countries, typically given to knights or baronets. SERENITY is a title of honor given to members of the Order of the Seraphim, which is the highest order of chivalry in Sweden.
