Ammo standardization , with BAD choices . The only people that liked the 223/ 556 , whatever you want to call it , crap is crap were the Americans . NOW the military has finally admitted its horrible , and needs replacement to a bigger projectile . They knew it was junk when it got its first combat test in Vietnam . Its inadequate in every way . The military was too deep into it , to turn back , but they knew they made a mistake . Americans do best when we go our own way , re adopt the 30.06 , and be done with it . NATO did what it was designed to do , but now the need is gone . The Soviet Union is dead , and its not coming back . Europe has recovered from WW2 quite nicely now .
