Using a rather simple comparison, between shooting a person who stood there stationary versus shooting a person who kept running around, which one would be easier to hit?
Even a dimwit knew the answer.
The crux was, the abilities of some shooters were distinguished by their every movement.
Even if one did well with a stationary target, they could still fail terribly with a moving target.
A hundred-meters target was already the limit for most people, much less a two-hundred-meters moving target.
Even training at an outdoor shooting range was easier than training with a moving target.
This was because it was easier to shoot a person than a target!
If you were asked to shoot a person who was running straight in the eye, it would be a difficult thing to do.
The two-hundred-meters moving target was such a concept. The dot at its center was even smaller than a person's eyes.
