So, we looked at sergeant majors and officers. And as a result, a bit of Wikipedia.
Marine equiv, Corps Regimental Sergeant Major.
Air force equiv.
And, umm, the army bloke seems to get an OBE on exit from the posting, the marine and RAF an MBE.
Anyone know why? Or is it just that the army thing’s been around such a short period that it’s entirely swayed by that one bloke and his gong?
