...just because one holds a Commision means nothing when It comes to knowledge and professionalism, you can have good and bad in all ranks, to say because a person is commissioned that they are better is simply not the case.
Not so much "better" as quallified to lead. We all know the examples where Officers are followed only out of a sense of curiousity, but in general, those selected for a commission have passed, or been assessed as, having the personal qualities and attributes required to lead. Service training reinforces and develops those skills, but the individual needs to demonstrate they have the potential in the first place.
As to your point about knowledge and professionalism, a good Officer will always recognise where to go for detailed or specialist knowledge to support a broader decision, and that is usually the tradesman and technicians performing the tasks on a daily basis.
So not so much better, just taking a different view of the issues.
