Ka-52 in Russian Air Force

So what, two helicopters were damaged and explosives were found on an Mi-28 the next day... totally incompetent... attaching explosives should be done near fuel tanks to start fires and burn out the targets completely... what a joke... even their terrorists are two bit amatuers.

is it so simple for any saboteur to destroy a hardware in a russian(not ugandan) military base?

They are clearly dressed in military uniforms in the video, so I would think they probably had fake documents to approach the aircraft and the explosives they had to use were tiny to make them concealable which lead to damaging the targets instead of destroying them.

Can the Ka-52's radar easily detect tanks, artillery, SAMs, and other metal objects hiding around trees or bushes from standoff distances(15-30km)?

Easily is a strong word... moving targets would be easiest to detect and allow the system to draw the weapon operators attention to it with zoomed in optics to allow proper identification.

But trucks and cars and tractors and all sorts of other things are driving around the place in the enemy rear areas too... not all are military targets and you would seriously have trouble telling which is which from a distance... remember these vehicles can operate over enormous areas and still hit targets because of their firing range, and they really don't have to move very much... they will be camouflaged and move only when critical and likely move from covered areas likely inside large buildings like sheds of other large structures out to fire and then retreat back to cover where they can be supported and fixed or reloaded or whatever.

The period when they fire and then go back into hiding will be 5 minutes maybe... even with quite heavy drone coverage you might only have a drone every 20-30km, so when it fires you might have a drone 20km away that can turn and look with massive magnification zoom optics to look for the target... it could turn and head towards the firing but at 150-200km/h it wont get there very quickly and HATO will likely tell them when attack helicopters or aircraft are operating nearby so they will lay low when that is happening.

In a panic an artillery vehicle like an M270 or M109 could drive into the side of a house and from the outside would be very difficult to spot.

They might kill some civilians doing that but they wont give a shit and when they hear on the radio that the helicopter is gone they might pull out and drive off to somewhere else.

Of course as I have mentioned with HALE and MALE drones loitering around with super powerful cameras when the helicopters leave they might remain and watch and find targets and watch where they go so instead of killing that M109 they find the building it goes to eventually.

If the Orcs have any brains they will have dozens of different large buildings and sheds set up for these vehicles to drive in to hide like a halfway house for escaped prisoners... transport ammo to these places so when the vehicles arrive you can top up their ammo and fuel and do any maintenance needed and then they might put a tarp over the back and drive it to the next building and then on to another firing point and another building.

Different artillery vehicles moving constantly from safe building to another, keeping radio and phone conversations to a minimum so they don't alert enemy EW.

The orcs are not stupid.

This will be an excellent opportunity for the Ka-52s and Mi-28NMs to get operational experience against enemy equipment and the rear IR and radar signatures of enemy equipment can be captured and examined... they will have massive hard drives on board recording the signatures of everything they scan or view with thermals and digital optics so they can review what they spotted and use software to recognise automatically the targets they are most interested in if they have not done so already. With the real vehicles they can refine and improve the performance so it will work even better perhaps at much greater ranges.

Note the description says the improved Ka-52 increase the detection range of optics by double and that will be IR and digital video, which means the radar can already detect targets at good range but now they can zoom in and identify targets optically better with the upgraded sensors... likely at distances they might not even know there are helicopters flying around nearby.

The US wouldn't even take helicopters to the conflict in Kosovo because they feared MANPADS in the hands of the Serbs... in this conflict in the Ukraine it wouldn't matter which side the US was on they would not send helicopters or CAS aircraft to support either side because of the risk of getting shot down.

Americans don't like fair fights.

If they had air superiority, many of those AAA & ATGMs teams would be suppressed by their Su-25/34s.

This says it all doesn't it?

Air superiority means you have an advantage in the air and you can take control of areas of air space when you need to, so when you attack somewhere with ground forces air superiority means you can shoot down any and all enemy aircraft that rise up in response to your attack and your aircraft are free to support the ground attack.

The next level up is Air Supremacy... when enemy aircraft take off from where ever they are hiding they get shot down and anything they launch gets shot down too... that is pretty much what Russia has right now in the Ukraine.

It is also what HATO had in Kosovo... yet despite that from the first day to the last in both conflicts enemy AD systems operating on their own were still a threat.

There is no level of air superiority where the dominant side can destroy ATGM teams and soldiers with HMGs and light cannon pointing at air targets... such a level simply does not exist.
