Actually, it was adopted for a number of other, not retarded reasons. The round is lighter so a soldier can carry a greater number of rounds. The muzzle velocity produced is higher so the round has a flatter trajectory within its effective range. The probability of a target being grievously wounded rather than killed is greater when compared to the 7.62x51mm round, in a battle a wounded enemy is actually better than a dead one (most military AP mines are designed to wound). Recoil is extremely moderate, especially in automatic fire.

As a side note, its the 5.56mm NATO round and not the .223 that the military uses. Yep, they're different.
