M1 Garand at 1000 yards with iron sights.
I last shot an M1 at Fort Ord in 1958. We shot at various distances out to 1000 yards (with tumbling and reduced accuracy).
No, I take that back. Amateur propaganda.
Hey, anyone notice the RANGE that soldier was looking at via iron sights? Check the second image in the referenced article.
400yds...IRON SIGHTS.
USMC at one time required everyone to qualify at six hundred with iron sights.
My kids were taught to be comfortable with standard NATO rounds as well as the .243. My daughter was routinely hitting 55 gallon drums center mass with 5.56 and 7.62 at five hundred by the time she was fourteen. My son got there by the time he was fifteen.
There's no magic to it, just desire and practice. Yeah, you might burn through a lot of brass, powder, and bullets, to get there but that's where you have to be if you want to use a weapon instead of looking good carrying one around.
If they're going to be on your toes get used to picking fragments out of yourself and use grenades along with something like 9mm with full auto available.
Back day when I was on a cultural enrichment vacation the best I could do was an old M2 with a somewhat cranky selector; and I had to buy that from our Kit Carson. M1 Carbine ammo was never a problem, though, in fact they seemed glad to be getting rid of it and dished it out in surprising quantities to a platoon with exactly one weapon using that round.
I'm not bustin' your chops, I really just don't see how the range makes this "propaganda" in your mind. Explain further if you feel the need.
