The RN one was a lot more relevant; we had our trades, watchkeeping structure and department structured identical to what they did, and they had already done basically MARTECH, with getting rid of HTs, then bringing them back. They told us this before we did it, and recommended we just go to what we are doing in the future (with common training up to 3s, then splitting off to sub ocs)
Instead of learning the lesson from them, we did exactly what they recommended we not do and will be something like 15 years before we actually go to their recommendation, which was also our recommeded COA back in 2014 or whatever.
The worst part is it wasn't even for any good reason other than 'fuck the stoker mafia' (which I was told was a verbatim quote).
Someone probably was grinding an axe for 25+ years from when they did something stupid as a subbie and got corrected by the cert 3 on watch or something, and has basically screwed the RCN for a generation.
