Course Marshals should be armed! Anyway, where they hang out depends on the course. Sometimes they hang around the clubhouse and other times they roam the course in their little red golf cart on a power trip. When I was in the military we went to a course and the marshal tried to kick us because we had on tennis shoes instead of golf shoes. The proshop guy said we were fine and it wouldn't hurt anything. That marshal was a grumpy old man.
