Jeff,
I am going to both agree AND disagree with you.
Full disclosure, I am medicated as hell right now due to a back injury, so let me know if I need to just sit down and look at the flowers.
OK, here's where I disagree. The individual shooter should absolutely configure his gear for the immediate mission at hand. This is not based on what the CIF, Deltoids, or the Iraqi (or whatever flavor of little brown guys I'm working with) are doing in their mission box.
Here's where I agree, and I'm afraid maybe it's something that gets lost with SF guys if they're only training on the apparatus they have access to (i.e., as you said in your video, "The particular CQB range I have access to / use doesn't allow me to do something else" -- let alone what the Leg Squad or Platoon Leader can do under Leg Range Control rules, regs, policies, and permissions).
Your S2 / O&I guy should always put out in the Enemy Situation part of Paragraph 1: 1) What is the Enemy's Most Dangerous Course of Action, and 2) What is the Enemy's Most Likely Course of Action. You made a conscious choice for an optic-equipped M4 rather than a sexy suppressed MK18 -- did either of the 2 above influence that (consciously or subconsciously)? Yeah, OK, so we're facing the Yogi Biryani clan or the 98th Guards Division. What are they capable of doing, and what am I most likely to face on this mission? How will they fight?
You pointed out there's a Pavlov's dog automatic "This is how we do this" inside the apparatus. Death-Dealing barrel-chested Freedom Fighters -- not fighting past 100 yards outside the structure, and not fighting your way out of the target area, maybe with booger eaters on upper floors (of other buildings) shooting down at you.
Very few places are rigged for live-fire and maneuver shooting uphill, or at targets on roofs two or more floors higher than you -- on foot or from vehicles.
You picked an LPVO for the fight to and from the OBJ. How many ranges you have access to allow 180, 270, or 360 degree live-fire from the vehicle, using individual, ring-mounted crew-served -- and maybe LAWs and 203s, then allow you to maneuver off the truck?
The beauty of going west to Utah, Colorado, New Mexico, Arizona, Nevada, Wyoming, Idaho, and Montana (ah shit, this is gonna be expensive convincing chains of command) is there are National Guard and active ranges that allow you to do all this -- live-fire full mission profile opportunities and facilities to also practice immediate action from leaving the FOB to return -- not just on the target structure, and not just at JRTC/NTC.
Phase 1 -- get to the target.
Phase 2 -- actions on the objective.
Phase 3 -- fight our way out, against jack-wagons who now know I'm in the neighborhood.
Yes, I should best configure for the job -- and I have to be ready for both worst and most-likely contingencies. And NOT just after watching an old movie, or getting ready to go into an exercise box.
Do I need a long gun or glass for reach? Should somebody on the (objective) dismount perimeter security crew configure for a 7.62 self-loader or short SAW/PKM for muscle on the way in and out?
Rant off, still doped-up.
