I feel sure that I am not realistic about this subject, but it seems to me that the most important skill an infantry soldier can learn is marksmanship with his weapon or weapons. Supposedly the British infantryman, in 1914, was trained to lay down rapid, accurate fire at ranges out to 800 yards and they demonstrated that in combat in the early days of WW1. It seems to me that all infantry everywhere should have the skills and the weapon to achieve that same objective. Why carry something if one cannot use it effectively? Recently was shooting at a mansized target at 50 yards with a Colt's Combat Commander, 45 ACP and a Ruger Blackhawk 41 Magnum. Easy to hit with the Ruger but the Colt's was problematical. Not sure that a single action revolver would be all that practical in combat though
I'm not disputing your numbers. However as I recall the replacement cost for an M-16A1 rifle was only about $300 during the late 1980s.In 1966 840,000 M16's were ordered, at 92 million dollars, thats $109 per rifle.
To finally put to rest the "myth" about the Garand clip ejecting causing a noise which the German soldiers took advantage of, there is an article in the latest "American Rifleman," ( just arrived today) which debunks that. Several months ago another article addressed that issue with WW2 American veterans and they thought it was untrue. That no one in combat would be able to hear the "ping" or I would call it a "ching" of the clip clearing the breech of the rifle. This latest article recounts the experience of some American veterans recently having a reunion near Bastogne, Belgium. Some older men observing the festivities nearby were identified as Wehrmacht Vets and they were asked if they used the sound of the clip being ejected as an advantage in combat. They all laughed and said it was ridiculous because no one could hear that noise in combat and even if it was perfectly quiet no one would know whose weapon was being cleared or reloaded.
