While technically in the .22 caliber center fire rifle family, the .223 Remington (5.56mm) is almost never refered to as a “.22”. That is reserved for the rimfire family of rounds (.22LR and .22 mag).
The Russian 5.45mm round is just called that, and makes up a miniscule proportion of AK’s in this country. Mostly because the ammo is limited to surplus.
I agree with the basic premise of this story, I just think they should keep their facts straight. It’d be like me calling the 1911 a 9mm handgun. Possible, but not typical.
the 5.45 round has been greatly gaining in popularity due to the cost of it. In fact there are several manufacturers now chambering AR15s in it. Before my tragic boating accident I’d bought 1080 round cases of it for ~10c/round.

The 1911 was made in 9 mm many years ago. I used to have a Colt 1911 9 mm. Didn’t even have it long enough to fire it.
