Always thought that was the kind of weapon they should issue to everyone, not just a 'designated marksman'...
If true I could see similar concerns raised about a .308, now that the infantry is open to females. The usability of everything, body armor, harnesses, weapons, have to be considered through the additional lense of a subset of soldiers with smaller stature and less body strength. The DoD did make a big show last year about releasing a new X-back helmet to accolade ponytails.
