How to Defensive a Rifle

When you pull the trigger on a rifle, it starts to fly. It's on a ballistic trajectory. And so what that means is you have to detect the launch of the other projectile. You have to track it and calculate its future trajectory. Because bullets don't just go on lines. They don't like lasers? No, they don't. Not like they do in Star Wars. Is it just because of gravity and wind? Well, air resistance. Drag. There's all kinds of other things. Like the fact that the bullet is spinning matters because the Magnus effect comes into play and the bullet will fall in a certain direction.
