Yes. I first came across "Petronius" when I was in the army (not, I should make clear, the
Roman Army)! That was another organisation where we would never quite have finished completing the earlier "change of plan" before yet another was foisted upon us!
And, of course (and sadly), this continues in the present day, what with the constant "juggling" going on in Westminster.

We had Brigades ... then some bright spark came up with "Field Forces" ... then (a few years later) it was back to Brigades. Same blokes, same barracks, same kit. New paint job!
My old mob (the REME) was traditionally organised in "Workshops" (and why not, for that's exactly what we were ...
field workshops, usually ... all of which had a proud history). Now I see they're Battalions. What [censored]! The
infantry has Battalions. Why can't "they" leave well alone? That's the trouble (well, one of the many) with this country, there's too many clueless meddlers about ... which wouldn't be so bad, just as long as they were kept well away from having any sort of official influence (interference)!
