>>The XM5 and XM250 represent the biggest shift in Army small arms in more than half a century. The Army has used the 5.56-millimeter round since Vietnam, and the shift to 6.8-millimeter will likely inspire many allies to make the same move. However, the most important advance is not in the new rifle or ammunition, but in the new XM157 fire control optic, which automatically judges the distance to target and corrects the user's aim. Such an advance, which helps shooters hit a target at longer ranges with minimal training, is probably the most important advance in infantry small arms in a century. <<
