Summary
Germany’s government approved a proposal allowing the military to shoot down drones over critical infrastructure as a last resort.
The move responds to rising sightings of suspicious drones, particularly since Russia’s invasion of Ukraine, with concerns over espionage and sabotage.
Recent incidents include up to 10 drones spotted over Bavaria’s Manching air base, raising security fears.
Previously, the military could only force drones to land, redirect, or issue warnings.
Well, if we’re talking about a policing role, it may be fine.
In war, if Country A and Country B are arm-wrestling, and Country A can launch a drone that costs a tenth of what Country B’s missiles do, you can probably guess that Country A is going to keep sending drones, because that’s a pretty favorable exchange. Gotta worry about what happens if it scales up.
But if we’re talking a policing role and don’t expect hundreds or thousands of drones to be sent out – like, the aim is countering espionage or sabotage – that might be okay.
Now, granted, one possibility is that someone might try to figure out a way to send large numbers of drones to do the above, but then that starts to stand out. I think that the current situation is probably more of one where the concern is that malicious drone operators are trying to hide in the noise created by benign drone operators. We don’t easily know whether a given drone is just some random person flying a drone where it shouldn’t be, or whether it’s someone trying to gather intelligence. But if spies start launching a hundred drones at a go, it’s going to be pretty obvious that it’s not just some random person making a mistake.
EDIT:
I remember just reading about some kind of programmable-airburst SPAAG that Germany’s sending Ukraine, think it was on a Boxer chassis. Assuming that Germany isn’t sending every one of those that they have, they probably have some to stick around sensitive areas of their own.

So if you plonk one of those in the middle of a military base or whatever, you’ve got a sphere of something like 3km radius.

It also looks like there’s some fancier thing that has both a gun and missiles.

Assuming that the “Group I” here is the same as the US classification scheme for UASes and Germany isn’t doing some unrelated-but-similarly-named classification system, it’s intended for use against fairly small drones:

Presumably if it’s Russian it would be quite large or if it’s small it’s piloted by some one relatively close on the ground
