IZInt,
Thanks for starting this thread. I too am tired of the gun rag review on weapons and performance plus the every present use of Blackhawk Down as justification for problems with the M4/Ar-15.
I carried an M4 (C8) in Afghanistan in 02 while attached to 3rd Bde of the 101st. After Operation Annacoda, there were no complaints in any of the AARs concerning the M4 or 5.56mm. Concerns were about training and upgrades to the rifle such as improved optics or upgraded M68. About a month after I get home there are these "official" reports quoted on the internet and gunrags concerning the complete failure of the M4. They even quoted parts of the AAR put cleverly changed the context. People have agendas and sometimes reality has a strange way of ruining a good concept.
Soldiers fight as teams with other weapons systems to support them. 240B, SAW, snipers rifles, DMR type rifles, Mk19, M2s, etc all work together. There is no universal weapon. Each weapon is like a tool in the tool box and the platoon leader maximizes the effectiveness of the tools he has. He trains hard and uses what he has the absolute best. In urban operations where ranges rarely exceed 100m, the compact nature of the M4, couple with the ammunition load and the mature use of NVGs and PEQ2/PAQ4C allow troops to dominate particularly at night. Night and urban fighting is a significant part of the future and the M4 is doing a great job. But for those who love the 7.62mm, the platoon and company have them in 240Bs and sniper rifles and now some m14 DMR rifles. It is all a balance. There is no perfect weapon, there is no one tool to solve all problems.....well a JDAM kind of is but that is another story!
Rest assured the M4 is doing exactly what it is suppose to but not everyone needs to have an M4 nor an M14 or anything else for that matter. A balance of weapons allows the platoon to do its job.
People without operational experience often relate combat to an OK corral type engagement, two or three fighting two or three badguys separated by distance X using cover Y and ammunition Z. They then anylize it from that perspective drawing universal conclusions. If they had an M14 they could of shot them out to 600m! they would say, but in reality that is what they have the DMR, sniper and 240B plus all the bigger stuff. This looks good in a movie but there is more to it in reality. What about the platoon weapons det, the tank that is supporting them, the APC or gunship that is supporting them? Three guys don't attack alone. Everyone is part of a team not just a couple of individuals. Until the plasma rifle in the 40 watt range comes online, it is a balancing act, one that the M4 in my opinion is part of and doing well. The army and marines are reacting to changes and modifying the tools in the tool box...as they should. This demonstrates the flexibility and adaptablity of the modern soldier. Adapt, improvise, overcome.
The example of the MPs who recently handed the insurgents their asses is a good one on balance and most importantly training. The leaders in the team recognized the importance for aggressive and realistic live fire training. The result was obvious. Days prior to the incident they had just completed an live fire range which in essence, rehearsed the very attack they responded to. Training is the key, not bigger calibers or different rifles. Use what you have to maximum and train your people to the highest levels. I remember the motto More sweat less blood. I hold this true, train hard.....
If you are talking being an armed citizen particularly fighting mutant zombies, your choice of caliber might be different. I am not up to speed with terminal ballistics on undead zombies but the fragmentation threshold or penetration of the 5.56 might not be sufficent. I defer to those with more experience in this area.
What I choose for HD defence is certainly going to be different from what I use overseas in combat. Firstly and most importantly, I can select the rifle and ammunition that meets my needs as I will be alone. The factors for this selection will vary greatly to the task and the pros and cons of different systems. Secondly I have the ability to somewhat rehearse and control the circumstances of the incident particularly in a defensive posture...something troops don't get the ability to do.
So in short, what the troops have is fine. Training is the key to success. Train hard and often. More sweat, less blood.
