Countering drones is the new question, and one of the key ones, not just in this war, but our day and age in any war. Tiny FPV drones with a small explosive charge enough to take out a person are cheap. Even 3rd guerrillas and terrorists can afford them.
In the Russo-Ukrainian war so many are used, and so many people are targeted, that just by the number, they'll come up with various techniques to counter them - and even the attacker side will know about them right away (and they can pass on the experiences to own troops, who could test them).
Electronic interference works, or lucky shots from shotguns, but it's interesting what this guy does in the video. He fires at the drone, and when it dives onto him, he ducks to the ground. For this maneuver, first one have to notice the drone, and keep an absolute level head. He looks quite calm, and walks away like nothing happened.

I'm thinking perhaps some kind of a net gun also could be used.
