Herald -- A person who is trained to function in one or more of the areas defined by the College of Heralds. A herald is an officer of the SCA. There are a variety of types of heralds, but they mainly break down to three areas: announcements (on the field of honor ["Field Herald"], general announcements -- sometimes called "duty" ["Duty Herald"]), master of ceremonies for court ["Court Herald"], and name/device/armory consultation ["Submissions Herald", or "Research Herald"]. There are other duties performed by heralds, including keeping track of the Awards Lists, and more. Note that not all heralds are good at or have an interest in all aspects of the office, so a Court Herald may not be interested in name research and so on.
Marshal -- A specially trained person who oversees combat activities.
Arts, Minister of -- The Minister of the Arts is an officer of the SCA whose job is to foster the arts in whatever means he or she can. This is often done through competitions and arts displays. The Minister of the Arts often works closely with the Minister of Sciences, and in some Kingdoms these two offices are combined into one ... The person holding the office may prefer to be called "Master/Mistress of Arts" as their job title.
Chirurgeon -- (pronounced kier-ur-jun, or surgeon or ...) An officer with first-aid training who stands by at events to render assistance as needed. Chirugeons are required to have formal qualification, at least a multi-media First Aid Card and CPR. The Chirurgeon may have a pavilion on site at an event, which would then be flying the banner for that office. This banner is usually red, with a white drop and a charge called a "fleam" on that -- it sort of looks like a weird '7'. This is the place to go if you have had an accident and someone is hurt ... NOTE: If an accident occurs and you are not comfortable trying to pronounce "Chirurgeon", just cry out for "Medic" or "First Aid" or something of that nature -- help will come running -- don't stand on formalities when someone's been hurt!
