Has there been an occupation amalgamation yet that provided any benefits at all, instead of ******* things up? None come to mind.
Actually, in the Navy, we successfully amalgamated the old sub-surface weapons mechanics with the surface weapons technicians to become weapons tech in the 60's. Then more recently, the naval electronics technicians amalgamated well with the naval weapons technicians (after their trade upgrade for the new frigates) to provide us with the current weapons tech trade.
We also amalgamated the old Fire Controllers with the Electronic Warfare technicians to become the NESO trade.
So it can be done when logic dictates.
Now as for the engineering trades, when you consider that more and more of our ships are in the category of electrical propulsion ships ( the MCDV's are already there, the AOPS will to, and there is a good chance the CSC's will have electric drives), which means that electrical generation, transformation (do you know what a thyristor is and do?
) and distribution at high voltages is getting to be a more important component of the ship's system, it's getting more and more difficult to figure where electrical work begins or end and where mechanical begins or ends.
Those two trades have to work more closely than ever and each needs to have a good basic knowledge of the other's systems. Thus, it makes some sense to have them learn both types of system while they are in the shipboard system learning phase of their careers. After that some specialization in one or the order seems appropriate, and by the time they get to the top job, on a ship with electrical propulsion, who's to say that its more important to have an electrician or a mechanic in the position of CERA? So they both could have access to such posting.
The real surprise is that they want to amalgamate the hull techs with those two trades. Who will become the welders and fabricators of anything metal or wood onboard? The "mechanical" guys? wouldn't that take away from their time for maintenance of systems? The electrical guys? they would be even further away than the mechanical personnel. It makes no sense to me to put the shipwrights in the mix. Their skill is too highly specialized and need constant practice to keep the craftsmanship level high enough.
But just the electricians and mechanics ought to be something that can be made to work well.
Now if someone could just figure out proper specialist pay for them, and in particular a good system of "charge" money, everything would be fine.
