We have Change of Appointment ceremonies for RSM/SSMs within the Army. We also do Mug Outs at Troop or Sqn level for all pers who are posted/moving along so they can get recognition.
There are ways and means to do this are all levels, and it starts with the Pl/Tp/Flt/Div Chains of Command putting the effort in to do so. I honestly get the vibe from this thread that there is something very wrong with the morale and well-being of folks wearing Blue in both shades.
I pity you all if a CoC parade has everyone below the rank of PO1/WO sharpening the guillotine.
Mug outs, and change of appointments I have seen have all been relatively informal, and more of small "ceremony", whereas Change of Command parades tend to be a "parade" with marching and all that... People aren't saying don't mark the change of command, they are saying a parade is hangover from the past. Have a ceremony, make speeches, hand out flowers, etc... just don't make people march up and down the square so the COs feel special. If you want parades, make them about the whole unit, or the whole CAF. Have an Ortona parade, or a Battle of the Atlantic parade, they serve a purpose for all members, not just the "aristocracy".
Lastly, I'm not below the PO1 rank, and I'm not sharpening any guillotines...
So firstly, we do have parades for ongoing RSMs, it's called a change of appointment (or change of stick) parade. I sat through one today, it had a reviewing officer and took 30 mintues.
Secondly, only a single member of a unit has the delegated authority to command on behalf of the superior commander and assume risk (within that delegated authorities and risk matrix). Yes, I'm sure a ton of our traditions are rooted in 18th century British classism, however if you want to think a S3/Pte/Avr has the same significance when they're posted than the CO, you've missed the boat here and maybe are better suited to the public service.
As I mentioned above, I've never seen a whole unit parade for a change of appointment, if it happens it's just as silly as a change of command. Have a ceremony, broadcast it on Teams so the whole team can see... Just don't make people spend days marching up and down a square so that Col/CWO Bloggins feels special.
Ah... the classic, if you don't see things my way, maybe you should quit line. How has that been working for the CAF lately?
