Actually the ranges stated in the OP was 1000 and 2500 feet. That translates to 333 and 833 yards respectively. I agree with another poster that it’s not the platform but a caliber issue. I find it hard to believe that the enemy is engaging our troops at those ranges with iron sights or a scoped AK for that matter and scoring hits. The AK may be known for working well in a sandbox but its accuracy is horrible at those ranges. The ballistic info for the M4 firing the M855 62gr (green tip) at 300yds the bullet will still be traveling at 2,072 ft/sec, and retain 591 ft/pounds of kinetic energy, dropping 7.3 inches from a 50yd zero. No bad but not that great either at those ranges. Still lethal if a vital area is hit. The .308 would be the better choice for those longer shots (800 yards plus) and it’s still in the inventory.
Only two defining forces have ever offered to die for you:
...Jesus Christ and the American G.I.
One died for your sins; the other for your freedom.
