its really un ethical and so coward . f.u.c.k. china and dji the mavic three is more than a nuclear weapon in this war on both sides ... how people are diying is totally un ethical...
i really cannot inderstand the russian side!!! the soldiers can shoot it easly if they aim...
the grenade took 3 seconds to ground so the drone is only 100m above,,, they can shoot so easily... soldiers only group instead of fleeing and shoot without aiming!!!!!
There are several methods to counter them but because of cost and widespread usage and low cost of drones they cannot be adopted widely. The em rifle that is generally employed against these types of commercial-modified drones has some flaws as well. There were some videos of jam resistant drones that were not effected from the em rifle pointed at it.
Assault rifles won't reach high enough when drones escape to higher altitudes and sniper high caliber rifles would be too bulky to carry around as well as targeting a flying target above several hundred meters would be very difficult. In the above video drone interceptor(around 2:48 mark) can be more useful with a kamikaze-small explosive option that can be used to target drones at higher altitudes instead of the proposed net throwing solution in the video.
Also the video mentions about lasers to take them down however in my opinion instead of taking them down with a hard kill a soft kill laser option is possible with a cheap laser pointer scoped rifle that has sufficient high power output that can block optics of drones. After the drone is detected a laser-rifle with a scope can jam its optics so it can't guide artillery or drop precise bombs on soldiers as long as its optics is distrupted. The rifle won't be heavy and lasers can reach several kms with high power blinding output easily.
This would be a temporary solution however as soldiers need to call support and escape to secure positions while drone optics is blocked by laser. It can be a somewhat cost effective solution and would work better against em jam resistant military grade quad-copter drones.
Detecting the quad-copter drone before it attacks would be the most difficult part as they are cheap small and high in numbers local solutions need to be developed for equipping soldier groups. Air defenses for other options can't cover large areas or compete against these widely proliferated small low cost drones. A possible detection alternative is Lidar. Drones can escape the radars being small but they can't escape lidars from short ranges. For short ranges and fixed positions like buildings or air defense sites lidar equipped vehicles can be used for detecting mini-drone attacks.
For a cheaper passive sensor early warning option acoustic sensors come to my mind tuned to the buzzing sound of quad copter drones. It needs a good filter to avoid other sounds and sound recognition processing to identify the drone. These can be installed on long poles mounted inside or near the trenches listening upwards for drone sounds and act as an early warning system for soldiers in the trenches maybe.
Below example uses a microphone array as an acoustic sensor. It also uses radars and cameras but to make it cheap and widely available to be equipped by soldier groups in trenches there is no need for radar but microphone array and cameras are enough for early warning and short range detection.
