I also dislike the term. It feels concocted to evoke “tacticool” vibes.

Unless you’re pushing new firmware onto a drone in Ukraine, FDE is stolen valor.

Might I interest you in "In the trenches" and "war stories"?

Ehh, I don’t think folks are claiming to be active duty or former military personnel, which is the bar for stolen valor accusations in my book. I agree with the sentiment but not with the determination of finding fault. Folks hired for a specific role rarely pick their own job titles.
