The gun mags are the biggest culprit in extending the issue. As far as I am concerned, particularly from the CF's perspective....there is no issue. There have been no complaints concerning lethality or performance. People often forget that the army fights in groups with a variety of calibers, all designed to do different things. Ask an M14 fan to clear a building at night with NVGs and he will be longing for an C8....I guarantee it. The counter arguement that the 7.62mm is better at long range....sure it is....but the majority of engagements are under 300 metre....in fact most are rock throwing distance....so the compact size and manoeverablity of the C7/C8, particularly at night, rules. If the target is at longer ranges, a platoon has, a C6 machine gun, 25mm, 155mm high explosive and 2000lb JDAM.....were pentration and lethality arguements are mute. As Kevin said, there is no problem....mostly from those who look at the fight from a one bullet vs one bullet perspective that seem to perpetuate this arguement. Trust me....all is well. The gun mags and armchair warriors will tell you otherwise but having carried an AR type in Somalia, and Afghanistan, I never felt underarmed or prepared....
Merry Christmas.....say a prayer for the troops in harms way...
Cheers
