Thanks for picking this up. This is probably one of my favorite titles right now, so I'm very happy to see it get picked up by somebody.
I don't see any major problems right now. It's a good scan, and good work. I wish I could offer some feedback on translation, but all I can say is the English reads easily and comes across as being good.
You're forgetting about ensigns.
(And in this setting, probably about cornets too.)
