Okay, so have you ever played with a bunch of balls at the same time? Like throwing them all in the air and then trying to catch them all at once? That's what we're talking about with multiple rounds simultaneous impact.
When we say "rounds," we mean bullets that come out of a gun. So imagine instead of throwing balls, we're shooting bullets. And instead of just throwing them all up in the air, we're shooting them all at the same time.
When we shoot multiple rounds simultaneously, that means we're shooting a bunch of bullets all at the same time. So instead of just one bullet going really fast, we have a whole bunch of bullets going really fast all at once.
This can be useful in some situations where we want to hit something really hard and really fast. But it can also be dangerous because there are a lot of bullets flying around and it can be hard to control where they all go.
That's why we have to be really careful when we use multiple rounds simultaneous impact, or when we're around people who are using it. We always want to make sure we're safe and not putting anyone in danger.
