Russia has published a directory of Ukrainian FPV tactics with diagrams, and suggested countermeasures.
The descriptions are basic, but the 19 separate listings are a reminder of how flexible and valuable the FPV system has become.

May as well do them all.

Last one.
If there’s any interest, there are some text pages of suggested countermeasures that can also be machine translated.

There has been interest in this Russian document on Ukrainian FPV tactics, so machine translations of the interesting section on Countermeasures have been added to the post.

FPVs with fiber optic cable control and video are immune to jamming, but there are also many other advantages over radio control.
Independence from terrain means freedom from line-of-sight limitations for both drone and the operator, who no longer has to seek a high location.
1/
Fiber FPV video is high definition to the full capabilities of the camera.
Video does not degrade with jamming, terrain, distance, or weather such as rain or fog, as radio video does.
Clear HD video allows more accurate targeting.
2/
The absence of a radio video transmitter significantly reduces battery consumption.
The radio transmitter gets very hot, so the FPV can be in stand-by mode no longer than two minutes in hot weather.
Fiber FPVs can be in stand-by in an ambush site for up to 12 hours.

The rare and exotic Russian PTKM-1R shaped-charge anti-tank landmine.
It was designed to disable Western MBTs by top attack where the armor is thinnest.
Acoustic and seismic sensors detect an approaching target 150-200m away.
1/ Image
Image
The landmine rotates and inclines toward the target.
When in range, a submunition is launched ~30m in the air.
Two little rocket motors spin it rapidly off-axis, allowing infrared and radar sensors to search the ground in a circular pattern.
2/ Image
Image
When the target is located an electronic fuze initiates the charge, firing an EFP capable of defeating most roof armor.
A self-destruct can be set from 1-10 days, and possibly also a vehicle counter.
There is a tilt anti-tamper, so the landmine must be destroyed in place.

Ukrainian radio expert Serhii Flash reports on his participation in fiber optic drone testing.
An FPV can make any maneuver, including flying backwards as in the video.
The key to this is positioning the spool away from the propellers as much as possible.
1/
The drone can fly over “…bushes, fields, forests, and houses” without incident, at a height of 50m.
The biggest threat to the fiber cable is apparently operators feet,
The cable can be rejoined, although not onsite,
2/
Image
Fiber optic cable comes in different diameters, and thicker ones are visible lying on field grass.

Recently recovered Russian Shahed-136 UAVs have satellite navigation modules (GNSS) with RTK (Real Time Kinematic) capability.
This means that a 4G/LTE modem can access the Internet and receive local positioning correction within centimeters in real time.
1/3 Image
Image
RTK GNSS use signals from both satellites and a local base station.
The data received by the base station is compared to that received by a mobile station, via a mobile network.
The base station also receives data from a local reference station, yielding centimeter precision.
2/3 Image
Ukrainian networks provide this LTK service, and their subscriber list could be scoured for certain parameters for disconnection.
But farmers have private RTK receivers used to exquisitely position their tractors in the fields, that possibly may also be exploited.

The Russians claim these are a new type of Ukrainian drone-dropped anti-personnel IED, with a pressure-induced electric detonation.
As with other new Ukrainian devices, battery life eliminates the long term persistence of landmines like the Russian PFM-1.
1/ Image
Image
A similar device was dismantled, yielding an explosive similar to German P8301 ( “Seismoplast-1, exploded in the video).
The fuze consists of two contact plates separated by foam.
When the plates are crushed together, current from the battery initiates an electric match.
2/ Image
Another variant with the same design principles.
