Yep. Sarge has 20+ years experience shooting a .226 or 5.56 from 100, 200, 300 yards. Most don't. The range in Arizona I used to attend - not to fire guns obviously since guns scare me - has a 200 yard area for shooting.
To hit from 150 yards, you need to be experienced. In the movies, when you line up a shot from 150 yards, the scope is as still as a picture and the reticle is perfectly aligned. In real life, the scope is jittering a millimeter here and there, and it looks like the reticle is dancing. Much, much harder than most think.
Sarge has simply done it for so long that it's like walking for him - he doesn't even need to think about it. Not true for all but the most experienced shooters.
