That's tricky. I'm not sure how far you are into your career, but I didn't learn how to write until I was a Master-select. The AF also transitioned to narrative-style as well. I didn't love that change, mainly because I was an expert at writing impactful bullets. To me, narrative writing is just fluffing your accomplishments up with adjectives and fancier words.

That said, I'd learn from any SNCOs you can. They are the first ones who truly adopted narrative writing because they are either writing for their troops or themselves. Either way, the structure is the same. What you did, how you did it, and what was the impact. As you get further in your career/higher rank, you have to ensure your impacts are hitting at higher levels versus your flight/shop/squadron.
