They can shoot their foot with a grenade launcher next. I’m already out of range.

Alternatively or additionally, I think oxygen plasma glows blue or green, because northern lights (near the poles, at least) are greenish.

Say you’re trying to defend against something like a Shahed-136. It can hit pretty much anywhere in Ukraine. You can’t stick an AA gun on everything that Russia might consider trading a Shahed-136 for.

As far as I know, the routine in the current war is - the AA gun is on a truck that moves 80 km/h, the drone comes in slower than 300 km/h, one or multiple truck crews position themselves on likely vantage points for intercepting, and the rest is luck.

Both of you are right.

It’s difficult, but how difficult depends on the task you set. If the task is “maintain manually initiated target lock on a clearly defined object on an empty field, despite the communications link breaking for 10 seconds” -> it is “give a team of coders half a year” difficult. It’s been solved before, the solution just needs re-inventing and porting to a different platform.

If it’s “identify whether an object is military, whether it is frienly or hostile, consider if it’s worth attacking, and attack a camouflaged target in a dense forest”, then it’s currently not worth trying.
