Those vertically-stacked twin mountings are Russian 25mm 2M-3M. Built in the 1950s for naval use, they seem to have cropped up in various places since...

Some tidbits from the field of drone warfare in Ukraine and Russia

Commercial drones like DIJ  'switch sides' all the time as the losses to EW are typically landed without much damage, and both sides have teams collecting these drones that then have software 'reflashed' for new owners. Something near impossible with military-grade drones . Commercial drones are actually designed to be vulnerable to EW as that is demanded by law enforcement agencies around the world , hence 10.000 lost drones per month.

EW against FPV drones is often a game of chicken as the EW effectiveness strongly diminishes with distance So EW gunners with handheld EW guns need to stand their ground in the face of incoming kamikaze drones, as the loss of video or control is often happening only very close to the 'gunner' and drone might still impact but the likelihood of hitting the intended target is very low if the feed was interrupted as quadcopters do not have a glide angle without power to the motors. Maintaining charged batteries on the front is a challenge as EW guns burn through batteries relatively fast , military grade drones are evolving to nonstandard frequencies to avoid the EW guns so its a constant adaptation game. Lots of supposed military grade drones , nearly all made in Ukraine use unhardened commercial transmitters so are easily taken down with EW   

FPV drone pilot's job is quite risky as their positions are extremely easily triangulated with passive sensors, so the use of repeaters is expanding, incoming FPV can often be detected with the aid of mobile phone apps.

Initially, DIY FPV drones had extremely low availability rates as many different and incompatible guidance and streaming types are made by folks donating them to soldiers on front lines,  lately bigger foundations and charities that make standardized designs and the manufacturing is being centralized so that drones function where ever they end up. couple thousand monthly being produced

SAM vs Drone wars, the best systems seem to be the ones with command-guided missiles not those with homing heads(heat signature is negligible), the multiple benefits are , missiles are super cheap(rumored up to ten fold difference in cost) the brain is in the launcher. an added benefit is that software upgrades upgrade the whole system, missiles need no upgrade.so even relatively old stock of missiles get a considerable boost in efficiency

The main issue with fighting drones with legacy systems is fusing these command-guided missiles as they were designed to shoot at planes, fusing is calculated to ensure max fragmentation of x number of fragments per square meter of the plane surface when detonated Y distance from the target  and drones being very small means X can be very low with same Y,  the fusing had to optimized for smaller targets, that is supposedly the mayor change that enabled GLMRS missile intercept rates to climb dramatically, detonating the warhead closer makes for a denser fragment field  ,drones and GMLRS missile are relatively non-challenging targets.The myth that drones are low radar observable because of composites is BS. relatively low RCS is purely due to size but often propellers reflections make up for smaller size, initially, the main limitation was the software that to aggressively filtered out of small and slow targets (birds and UAVs) 

Note SAM warheads do not have a circular fragmentation pattern but rather a cylindrical so ideally they detonate a broadside to the target  , radio command SAMs also often attack from the top to give the radar clearest tracking of both interceptor and target, these parameters had to be adapted to better engage smaller targets like missiles and drones.

There is an interesting video of a Supercam drone being attacked by Crotale system , the same type of system that downed the Bayraktar over Kiev, and it illustrates the whole fusing issue as missiles are detonating in front and in the rear of the drone but too far for a dense fragmentation field and at one point a fragment impacts the drone and cuts a wire sending the camera gimbal into 360 rotating motion while the drone was able to make it back and live to fight another day. 

GPS signal is practically dead in Moscow due to active jamming supposedly making lots of trouble for taxi drivers, drone attacks into Russia are seen beside the PR as an effort to force pull of SAMs from front lines ( for protection of Moscow they estimate they would need  over 50 Pantsirs to get even close to 100% coverage), fighting drones kinetically in a city is seen as an extremely bad option so EW is primary defense, they estimate 90+% of Kiev damage to residential areas is from stray Air defense missiles, current Ukrainian drones have very small warheads that are often homemade so most do not even detonate, and are in  some ways posing less of a threat than SAMs themselves particular if any larger systems would be used with 100+kg warheads

Interesting tidbit around Geranium aka Shaheds drones , folks that work on drone electronics , say that these drones used in Ukraine are visibly downgraded models , as they say electronics packages recovered and documented so far show there are number of expansion ports 'iranians' made that are not being used in these versions , given what has been seen in Iran shaheds have lots of upgrades availible  , so folks assume its ither Iran supplying export -Monkey models or monkey models being manufactured under license in Russia , reasons for monkey model is probably lower cost .

Everything that goes up must come down

Russians have a bunch of Himars equivalents already on hand , old projects that were passed over, by MOD years ago .folks are actually bemoaning that anything new is being developed ,when there is already a developed product .Not just show prototype but item that went through all the military testing, the 300mm six pack launch pods and satellite-guided missile is already in use

The lightweight 300-mm MLRS 9K58-4 "Kama", using 300-mm rockets MLRS 9K58 "Smerch", but made on the automobile chassis KamAZ-6350 or KamAZ-63501 (8x8), was developed by SKB JSC "Motovilikhinskiye Zavody" ( Perm) in the 2000s. The first version of the combat vehicle 9A52-4 MLRS "Kama" was presented at the Moscow Aviation and Space Salon MAKS-2007 and was equipped with one unified quick-detachable transport and launch container 9Ya295 with six 300-mm rockets. The dimensions of the sealed container 9Y295 are 7512 x 1130 x 996 mm, curb weight - 6.2 tons, empty - 1.42 tons. The total combat weight of the combat vehicle in this version was 23.6 tons. The crew of two people, the car on the march was disguised as a truck with a fabric canopy.

However, this machine MLRS "Kama" has not received development. The 9Y295 unified transport and launch containers with six 300-mm missile guides were also used on the 9A53 combat vehicle of the 9K512 Uragan-1M bicaliber (220 and 300 mm) MLRS, which was formally put into service in 2016, but has so far remained in piece copies .

At the REA-2009 arms exhibition in Nizhny Tagil (Sverdlovsk region), a new version of the 9A52-4 Kama MLRS combat vehicle was demonstrated, now equipped with a rotary 300-mm six-shot tubular launcher MZ-196 instead of the 9Ya295 transport and launch container. Accordingly, a special transport-loading vehicle (TZM) 9T234-4 was introduced into the MLRS, carrying six 300 mm caliber missiles and also made on the KamAZ-63501 (8x8) chassis. Tests of prototypes of the MLRS "Kama" in this version were carried out for several years, but in the end they were discontinued due to lack of interest from the Russian Ministry of Defense, which decided to acquire a modernized version of the MLRS "Smerch" performed by 9K515 "Tornado-S".

The reasons for the current reincarnation of the Kama MLRS in a “new look” and with guided missiles are quite obvious and are well described by Stalin’s legendary phrase addressed to the aircraft designer A.N. Tupolev about copying the American B-29 bomber: "Don't do it better, do it!".

 

This is what was much later bought as MLRS 9A53 Uragan-1M with twin pods 300mm or 220mm pods , vehicle that also near twice the size and weight 

9A54-2 "Kama"  was unveiled in 2009 differs by not using a sealed container, for use with all legacy 300mm missiles  , reloadable pack is about one tone heavier than the sealled missile pack

Then there is option on armored Kamaz 8x8 chassis

Great video. The tank does take two solid hits. 

From this clip, it looks like it take a close range (50-100m) hit from some sort of direct fire rocket.

2nd hit is weird. Looked like an artillery strike hits, then a half second later a smaller explosion hit the side of the turret. Not sure what munition this would be.
