I know a flak jacket is often a sign of a Jonin or Chunin is some cases, but I've always wondered why they don't just give everyone a flak jacket and have the color denote rank instead? A flak jacket is supposed to be armor, right? Why send your new recruits into a firefight without armor? :P

Flak jackets (Baki's aside) normally don't stop fuck all, anyway.
