Drones and how to kill them?

Wouldn't that also work with DIRCM though, assuming it was possible? The counter could also be easily countered by shifting frequency with the dazzler.

Possibly, though DIRCM may be using an IR-freq laser, which would be harder to design a seeker around ignoring.

The blue and green dazzlers are pretty tightly frequency-bound, though, just the nature of how those lasers are generated. For example, my blue laser says 405+-10nm for frequency range. Make a lens that is opaque between 420-390nm, blue-purple dazzlers are going to be completely ineffective.
 
I don't think it's possible to harden drones this small from microwaves while keeping them cheap and small. Poor bloody infantry will have to work closer than ever with their vehicle support in the coming years.
 
With improvement in lasers tech, just about every vehicle can fit pretty powerful blinding lasers if warcrimes is not a problem.

The end result of all this is not the removal of low cost, high payload means of moving stuff: "vehicles", but the end of infantry as the entire battlespace is filled with systems that can neutralize infantry with ease.

All it takes is someone to pull something off something like unrestricted submarine warfare.

DIRCM against imaging sensor (example):

Our paper investigates a means to increase the effectiveness of dazzle by modulating the laser at a rate close to the frame rate of the imaging sensor, i.e., a strobing effect. A continuous-wave quantum cascade laser (QCL) at 4.6 microns illuminated a mid-infrared focal plane array imager, modulated by either an optical chopper or by periodically varying the current of the QCL.

Cheap drone means standardized parts. It should then be possible to target a large aspect of drone camera with a single system.

Many people have figured out how to set the power for laser dazzlers based on detecting the reflection from eyes and then setting the laser output to just below the blinding threshold at that range. If they don't detect any eyes, it fires at full power.

More powerful lasers in dazzlers like those mean longer effective range to dazzle.

I don't see a modern military doing that unless they are losing really, really badly. Existentially badly.

I much more expect the first users of drones in that way to be terrorists.

It is pretty easy to fit blinding lasers on a drone, and the hardware can be more accessible than explosives. Some really insane stuff is feasible even if it just dealing with say, gang disputes.

Its like no military or law enforcement is really prepared for this stuff. It'd really be a shock if someone mass this just like the current FPV situation.

Steady flight of kestrels could help aerial safety soar

Perhaps a last line solution for drone defence could be using canister shot fired from a 25, 30 or 40mm grenade launcher mounted in an RCWS on vehicles, or by using similar calibres of canister shot fired from SPAAGs.

Jamming seems to be working quite well, according the the French Army chief, about 75% of all drone missions are resulting in failure in Ukraine. Jamming would effect the commercially available drones the most, which seem to have stopped being used for raids, as both sides began to manufacture bespoke drones last year. We will likely see this trend continue into the future as jamming is improved.

Seems helicopters are well suited for direct gun engagement of low cost drones (at least with some gun smoke ventilation). It´s great for the high speed designs that went neglected lately. A Cobra, for example, would fair well here probably with her ability to dive at high speed while still a stable gun platform.
