That's why you need all round vision from cameras. In fact this could have been done much earlier but now these types of optical systems are becoming dirt cheap compared to before.A flying drone is more versatile that one thinks. If you've seen the video of a Ukrainian FPV drone going after two Russian soldiers on foot, the drone is zipping around the soldiers like a fly who are trying to get away from it making contact while firing their assault rifles at the drone. They completely miss hitting the drone. It was only after one of the soldiers goes empty on his weapon, he throws his assault rifle at the drone hitting it and it explodes.
I read that all the MBTs that Western countries gave to Ukraine are all destroyed from these drones. You don't need the velocity of a tank round to at least disable a tank which is basically a dead tank. Look at all those videos of Hamas soldiers sneaking up to Israeli tanks and planting charges. I wonder how effective it would be having a wheeled quadruped robot roll up and plant an explosive. they're going to be hard to spot and soldiers are not going to be outside to spot them afraid of FPV drones going after them.
