With guides like these, I'm learning a lot! Notice, as we peruse a history book, that Johann's hat has crossed cannons and his coat has red trim: that's how you know that his job is firing cannons. The crossed sabers on Preston's hat show that he's in the cavalry, and the black chevrons (which look like "v" 's) on his jacket show that he is a Sergeant. As a cavalry soldier he would also wear big boots, but like Johann and I, he just has "bear" feet today.
