Further, the US Army is not looking for a battle rifle. It is looking for a precision rifle. Remember my comments about the balance of weapons suites. There are plenty of 7.62mm Machine Guns with the troops. MGs win battles. They are the firepower on the battlefield. For some people, there seems to be a gap of capablity, but it is not. The M110 fills a role, but the fighting is done with M4/M16/C8/C7s....and machine guns. Remember as well engagement ranges are generally very close and far. There is a wide selection of systems designed to meet these challenges. It is a holistic approach to battle. There is no universal rifle, no ultimate rifle. Combat is not two people faced off OK Coral style mano a mano. Combat is a dynamic and moving game of high speed chess. It seems simple to compare rifle ballistics and say this is better than that. If that is the case, why not have an even bigger caliber since people comment that the 5.56mm is no good? Because there is much more to it than the caliber. Fighting as a team is what soldiers do, and they practice it time and time again. Group tactics - firepower and manoever is what allows us to kill the enemy. Not the caliber of a rifle or having a designated Marksman. Canada does not have them....and we have been kicking some serious ass....
So try to understand that there are alot of smart people, operators and soldiers who spend their life in the profession of arms. It is not a hobby. Logistics, and maintenance might not be ###y....but guess what....no spare parts or trained support personnel and the coolest of rifles is junk....
