Think about the best military movies you've seen. Do they "dumb down" the technology? In my experience, no.
It's accurately portrayed. At the same time, it's not the center of the story. That is still the human component.
They spent a lot of time/effort in "Saving Private Ryan" getting the sound of the M1 clip ejection right. But nobody ever comments on or explains this in the movie.
Veterans watching the movie said they "got that right".
(I'm not saying that "Saving Private Ryan" doesn't bend reality in some ways for the sake of the story. But they didn't... have Rambo take out a platoon with his bowie knife.)
("Band of Brothers" is another good choice -- the mini-series precursor to "Saving Private Ryan".
Then there are, for example, some of the older, somewhat spartan but impactfully understated British films, whose titles I can't think of right now. It was actually films like these that I was thinking more of, when I started writing this, before those contemporary items came to mind.)
If done properly, such portrayals can convey a quiet, authoritative air that is actually more convincing than some of the "explained"... "exaggeration" and/or simplification that exists in many movies including some big budget production.
Aiding this might be spending some time actually explaining these things, in some depth, to the actors, so that they can portray them with some understanding, rather than simply parroting the script.
Of course, you might have to convince/sell a potential purchaser/producer on this idea, to help the technical content go down.
P.S. I should probably shut up, now.
But, I think there is something to an accurate portrayal that is the richer for not being too self-conscious (on screen).
P.P.S. A few random films, with different topics, where this might apply, that I'm happening to think of upon this unplanned attempt to come up with some relevant examples.
"China Syndrome" (although I'm a bit hesitant, having only seen this with commercials and while somewhat distracted)
"Traffic" -- the older, European mini-series version, from the 1980s
Watch "Eat Drink Man Woman" and see how much of a feel for 90's (upper classs-ish) Taipei you walk away with. (Although, admittedly, as I understand it Ang Lee brings a certain outside or cross-cultural perspective to it from his having spent significant time abroad.)
There are probably many better examples, but that's what my tired mind can dredge up, at the moment. And I think this represents a variety of things where authenticity enhances rather than confuses or degrades.
P.P.P.S. See P.S., above. ;-)
