The current (military) system delivers crews at a fairly basic standard
That's the point. They're at the same basic standard certainly as far as the ouput from Valley is concerned. If the personality/locality driven styles that you describe are allowed to develop without basic skills having substantial commonality and an independent standards unit in place to stamp out unsanctioned deviations from SOPs, who knows what disparity in operating practices might exist after ten years. It sounds like chaos theory!
