Wow...this is a topic that could, potentially, produce a very long and very interesting thread!
You have touched on one of the great mysteries of military ethos--the relationship between officers (esp junior officers i.e. to some extent Capts, but ESPECIALLY Lts) and Sr NCOs (esp WOs). We slam head-long, here, into the wonderful and fascinating balance between knowledge and credibility arising mostly from training (officers) and knowledge and credibility arising from training AND experience. To keep it interesting, its the less experienced of the two that has the comd authority.
I suspect that many on this list can--and will!--relate their views on this relationship, whether it is a good thing or not, how well it works, and whether and how it should be changed. But all that aside, it's what we've got, and what we have to live with. So, yes, you will find officers--esp younger ones--who are "headstrong" and don't realize the "power a WO has" (not just in an inf bn, either). The challenge for the WO in that situation is to figure out how to develop that young officer, channeling and focusing his/her "headstrong" nature into productive directions, while maintaining a professional relationship that protects the credibility of the officer as the authorized commander. It's pretty apparent where officers go wrong with this; they "blow off" their WOs and try to run the show by themselves. However, a combination of letting them make the inevitable mistakes, along with firm but gentle pressure from the WOs themselves (along with CSMs, Coy Comds, the RSM, etc.) can often shape them into decent officers. Another way to look at it is that it's better to have a young officer that needs to be reined in and steered right, than one that needs to be kicked in the backside to do anything at all.
Unfortunately, the NCO sometimes gets it wrong as well. I have seen cases (quite few, though, thankfully) of Sr NCOs who, for any number of reasons, "blow off" their officers and take over the show themselves. This is just as wrong, perhaps even more so. The WO plays a vital role in developing young officers; abrogating that role out of impatience, disdain, whatever, is counterproductive and wrong. Cases where the WO cuts the officer out of the decision-making loop or, even worse, openly marginalizes the officer, are massive failures by that NCO.
In the end, the decisions may be largely originating with the NCO; but if they're decisions PUBLICLY made by the officer, following a period of discreet consultation with the WO, that's fine. And the troops aren't dumb...they know it often works this way. And the WO and officer know the tps know. In a way, it's a dance, and everyone knows the steps. But the result is an officer who is learning, a WO who's passing on his/her knowledge and experience and developing that officer, and tps who have confidence in a productive, joined-up leadership team.
So, WO, you got your work cut out for you! But the result could be a fine, switched-on young officer, ready for bigger and better things...a good thing, yes?
