There is no Goal. The reality of combat is that soldiers are trained to what they are most likely to face. and Most likely they will always engage the enemy from 50m to 200m. Beyond that like i stated IA SOP would be the bring in additional firepower to either manouver closer to break contact. Lobbing ammo from 800m is a waste of ammo unless you are Talibanny
Design of a product and its ultimate end use are not always correlated. While a traditional def of a battle rifle is a full powered carterage today that line item in Orbat is routinely filled by M4s, AKs, HK636s, FAMAS, INSAS.
Agreed. Why the IA went for 762NATO is anobodies guess but the Army also wants 762/39 and 556/45 so your guess is as good as mine. The Americans seem to be working towards the 6.8mm hybrid solution.
So Far various subunits in IA has put the SIG through its paces and they seem very happy with it.
I received my Scout Shooting Merit Badge when i was 18. Along with the Scout Masters we had a USMC Small Arms Instructor and it was conducted at Yokota AFB, Japan. My merit badge was earned on a Winchester .22LR both with a 4x Scope and iron sites. I have also hunted a bit in Canada apart from spending time at ranges with friends who had been shooting since they were 6. So while i am not an expert at anything i understand a wee bit.
You cannot train anybody in 3 hours to shoot accurately and consitantly on any firearm (even if they are naturals). Training on Scopes is incredibly hard specially when you start going out to 700-1000m distances.
Secondly doing target practice is onething. Getting an average soldier to undertake accurate fire out to 800m under contact after having spent 3-4hrs patroling with combat load in desert/jungle/ravine etc terrain is a whole different thing. It requires hrs and hrs and 1000s of rounds of ammo to train that soldier where he should be learning to shoot and manourver with his squad.
