Can you imagine how hard that would be in that unit even if they had one? I’d be honored to pull a watch for them, but I think their standards and honor would nix that.
I imagine they still have one. You always need that guy to pull unexpected relief. Probably not “drop of a hat” relief, but, “Oh, man, Johnson just puked. Send out the next guard and call in the supernumerary so we can work him into the rotation.”
