The famous Bradley that mogged that T-90 has a drone jammer on the turret.

Apparently the average range of this type of jammer that AFU is using widely is 40 to 80 meters.
It doesn't stop drones from hovering 200-400 meters away and taking video of you with zoom lens; but it does mitigate a little bit of the suicide FPV drone threat...
...with one caveat...
...you've got to be moving. A jamming range of 40-50m means that if you're stationary; even if you jam a suicide FPV drone in it's attack dive, the ballistics of the drone will mean that it has a good chance of hitting you.
Rough figures...
Objects in free fall drop about 25 m/sec.
Average height of a 10-story building is about 30-35m.
A FPV UAV in power dive takes maybe 1 to 1.2 seconds to hit the target.
Bradleys are 6.55m long...figure an average speed of 7 m/sec so that a Bradley can clear it's own length through the aim point for the FPV UAV operator.
That's roughly 25 km/hr (or 15.6 mph).
Essentially, from the math above; if you have a EW Jammer...movement is life.
EDIT: I just realized that Drones themselves are causing combined arms. They force units to be mobile to avoid drone attack runs; which in turn makes the units visible and targets for other weapons systems on the battlefield.
EDIT II -- and of course someone pointed out that the NEXT generation of FPV kamikaze drones coming online will have machine recognition and AI tracking (currently available in larger stuff like Lancets); so they'd be able to track through jamming; unlike a remotely human operated UAV using a datalink.
