It sounds like you are angry. What I wrote is only my opinion. You can disagree with it if you like. I am not an expert by any means. And it seems you have put me in my place

( sarcasm of course). You are correct and I am wrong.

Feel better?
If you read what I had written I wrote that I cannot foresee using it as a LMG. In other words I was questioning the need for an ordinary infantryman to have a heavy barreled carbine when it will never see hundreds of rounds down the spout in a few minutes. If it did then the soldier is forgetting fire-discipline. Every carbine need not have the ability to mount a 203.
