Tbh, I always envisioned them as Lieutenants or Captains (very very new Captains though) just because they're so ridiculously young and adorable - erm, anyway, back on track.

Now that you mention it actually though, they would be higher up in that sketch, because they're talking about going to war (and then presumably tactics), and a Lieutenant and Captain (poss) wouldn't get invited to those conversations as they're too low down the ladder.

*bats away the plot bunny but it's too quick*

I shall get back to you on this!
