And 5.45 too, as in AK-74. Yes, range is too long and bullet is too powerful.

>Even in WWI rifles were outdated - from today's point of view - as they have unnecessary long range and they are only capable of single shots and the armies needed more dense fire and not more accuracy in a range where smgs were passable (but not optimal I give it you that).

Yes, range was too long, but range of SMGs was too short. They were effective only on <150m because of short barrels and pistol ammo. Frontline shooting in trenches requires more range, even maneuver combat requires more. Of course in cities and close combat situation is different, but it wasn't main area of battle.

Armies tried to use shorter carbines but didn't phase them out completely even after war.

Although topic is debatable of course.
