Tell me you don’t know what you’re talking about without telling me.
You don’t need to hit the bullet with a bullet. You just hit it with a shotgun blast or grenade, either destroying it outright or blowing it off course enough that it loses its energy and becomes ineffective. We literally do this all the time on tanks and humvees. It’s called a hardkill APS. The Russians had one working in the 70s. Modern ones are capable of detecting incoming tank rounds moving between 700-1700m/s, identifying which will hit the vehicle, and blowing them out of the air once they reach 10-15 meters away. All in a span of nanoseconds. It’s standard equipment on Israel’s MBT, and Germany, the US, and the UK have all field tested various systems and are considering making hardkill systems standard for the next generation of tanks and IFVs. Multiple companies across multiple countries make them for upgrade kits. Germany already produces vehicles with standard hardkill APS for their export market.
This isn’t crazy sci-fi technology. It’s just rocket science.
