It was one of the worst days of my life when they took away my M-14 and gave me that Mattel POS . Now I know there are those out there who think the .223 and it's military platform is the greatest thing since sliced bread . If you have been in combat in the jungle with it I'll respect your opinion , otherwise not!
I said the same thing, until I was issued the M16A1 and started using it. I found it highly reliable and effective. And by the way, I was infantry (2/502 Inf, 101st Abn Div).
What we must understand if VIETNAM IS HISTORY, NOT DOCTRINE.
We are talking apples and oranges here. In reality, in Vietnam, 90% of the time we didnt see who we were shooting at. In the jungle, its one set of trees shooting at another set of trees. Vietnam was about fire power. Vietnam had a lot to do with how much ammo you could carry. If I remember right, the basic load for the M-14 was 240 rounds, the basic load for the M16A1 was 460 rounds. Weight matters, we didnt have bottled water carried by HUMVEEs, we weighed whether we wanted to carry more water or more ammo. Our company trains supplied us once a week so we had to carry our rations. Most of us carried 5 qts of water. Nasty as it was, it came from rice paddies or mud puddles.
In Vietnam we didnt wait to see a weapon before we openned up, if we got fire from the tree line, we openned up on the tree line. And Villages, well, you get the ideal. Violence of Action.
That was a completely differant enviorment then what we have now. ROI is differant. You have a differant enviorment between Iraq and Afgan. The way I understand it, most of Iraq is urban fighting, where as Afgan for the most part, is mountain top to mountain top. Differant jobs require differant tools.
I love the M14 system. I used them in basic and AIT, I carried one in the 82nd before I went to SE Asia. I've used them for over 30 years in competition. I've use them in Sniper School (M-21) and have taught sniper schools with them.
The are extremely reliable and accurate to 900 meters. They, hold up, when deployed in SE Asia, they spent less time in the maitance shops then the Marines M-40s of the day.
BUT for "violence of action" as in ambushes you want the fire power of the M-16 systems. For engaging targets at long distance, not repelling an ambush the M-14 is hard to beat. A M-4 beats the heck out of a M-14 for room to room searches. Just like you dont want any rifle when crawling through some dark muddy tunnel.
So it boils down to, we need both, I really like the desinated marksman program, it fills the void. Its kind of like saying, which is best, a fighter bomber or a helochopter gunship. Fighter Bombers are great for laying naplam in the tree line, but if you want some one to start at your muzzle flash and work their way out, you need the gunships.
