It is in fact horse shit.

Ah so that's why the Army wants a $12,000 sight to make Joe's shoot better instead of giving them more ammunition to train with and why every single Army infantryman has a Marksman badge at the minimum and why every Marine qualifies as Expert on a flat range with range indicators
Top tier marksmanship training right there.
Average Joes are not getting hits past 300 meters reliably
"let’s examine the US Army’s fairly recent rifle qualification test. With human torso-sized pop-up targets positioned 25 to 300 meters away from the shooter, inside the maximum point-blank range of 5.56, range estimation wasn’t a factor. And yet, how well did the Army’s Soldiers score? Generally, not well."
This document is from 2021 and it's the US army Admitting that their marksmanship training is on decline.
"Let’s examine the US Marine Corps’ fairly recent rifle qualification. Firing at known distances of 200, 300, and 500 yards, the shooters benefited from range flags hanging everywhere, allowing the use of formulas like these to solve wind speed and direction. Despite external ballistics barely being a factor, qualifying as a Marksman was difficult, let alone Expert"
"Those were flat ranges, shooters weren’t exhausted or stressed, targets were easy to find, fully exposed, weren’t moving, and weren’t shooting back either. And yet reliable hits were difficult to achieve inside 300 meters, let alone 600 meters. Meaning, that despite the laser-like trajectory of the heavy-recoiling 6.8x51 cartridge and the features of the Fire Control Optic, despite its hefty price tag, NGSW is not going to buy more hits, because the NGSW program has no real answers to aid the fundamentals of marksmanship."
Oh and remember, M7 is only for 101st Airborne or better tier units. They need that $12,000 sight you see.
Meanwhile USSOCOM is fine with URGI, piston driven rifles with barrels up to 16 inches in 5.56mm and then they need to go further it's a DMR in 6.5mm CM or a dedicated sniper rifle in the same or .300 win mag or .338 LM
Or a machine gun.
