A few weeks back there was a quote of the day that basically called out the M4 as a bad infantry weapon, and much of the comments section was devoted to a debate over why the military will not (or should not) move to a different platform. I found a lot of the debate very interesting, but my question is, if you could build the ultimate main infantry weapon, what would it be? Also, because we are going all-out here, assume that both cost and influence from our allies are not issues.
