| Another interesting topic. New service kinetic energy ammunitions are capable, in test conditions from test barrels, of less than .1 mil dispersion. That means, at 1000 meters, the dispersion of the round will be less than 10 cm. That, in itself, is remarkable, everything considered.
But, real world accuracy is normally quite different. Tanks vary, crew skills vary, trunnions and barrels get worn, and so on. In the real world, 25 cm groups at 1000 meters is quite acceptable, while anything larger than 35 cm is not. Of course, every once in a while, along comes the "perfect" combination, when a crew will fire a 15 cm grouping. But, consider that even a 25 cm grouping means less than 10 inches!
The current acceptable standard is to be able to hit a one meter by one meter stationary target, either while on the move or stationary, at ranges of 2500 meters, 90% of the time. That has been proven to be achievable in most third generation western tanks. Why is that important? Because a well positioned tank will not expose more than one meter of turret.
Current soviet tanks cannot meet that standard, especially on the move, although they have come close while stationary. |
