 * This concept was invoked in the last chapter of the second season's manga, where it's mentioned that Admiral Leti decided to keep the Wolkenritter together because "A group of five has greater war potential", with Amy and Mariel agreeing. So...


 * The trope is played with in the drama CD, Sound Around, when Haruhi makes the SOS-Dan into a band and gives them the proper (from her point of view) instruments, though Yuki and Kyon's guitars are switched.
 * It's also arguable that whilst Haruhi treats Kyon as the The Big Guy (i.e. using him for all the menial labour) and Itsuki as The Lancer (i.e. promoting him to her second-in-command), she really sees them as the other way round, since Kyon is her Straight Man (and quite possibly love interest), as well as the one who gave the idea for the SOS Brigade in the first place, whilst Itsuki is just really there to back up all her decisions, and is also the tallest in the original novels (the anime for some reason made Kyon the taller of the pair).
