You are quite correct but you used two very important words - "premier warriors." There is no doubt that they can make full use of and derive benefit from that level of sophistication. The original poster asked about "defensive use". I interpreted that to mean, perhaps incorrectly, that it would be for an individual in a defensive situation. I benefited from some words of wisdom imparted by usmc03 on this site regarding home defense use of an M4 in which usmc03 commented that irons were preferred because "invasions happen quickly ..... not waiting for one to turn on electronic devices ..." and went on to recommend irons with a good light. Experimentation and testing convinced me. I use a Meprolight front with a foregrip mounted light. Of course, that's an M4. On one of my revolvers which has a rail, I use a light I mount on that rail and an integral red dot (though I recognize some of the liabilities of those) which is turned on by momentary thumb pressure. I never use one on a carry weapon and when I've had to use a weapon in the (thankfully distant) past, it was with actually very rudimentary irons; fortunately, I'm still here.
So, that's the reasoning. Special operations has different requirements than I got from the initial post. Also, those holsters which allow RDS are specialized and larger. I appreciate your comments but I think we are at cross-purposes.
