I still cannot believe these are new 1500hp engines, if they were, then they are the best gas turbine tank engines in the world, much better than those on M1.
I honestly think the solution is LIDAR for detection over relatively short ranges and fixed angled munitions like the ARENA APS system originally used to cover angles and directions that the threat would approach... obviously jamming and active defence like a dazzling laser that blinds or damages optical systems including visible and IR wavelengths would be important.
Make it multipurpose so it can intercept anything from a light drone to an APFSDS round and everything in between.
LIDAR would see up to a few hundred metres but could be designed just to detect within 100m or less for drones... drones are more difficult than ATGMs in the sense that they are flown and could shift target or approach at an unusual angle that initially might not appear to be an attack flight profile, so the system needs to detect and threat assess and decide to engage very swiftly, but like anything on the battle field you need good awareness and the right systems.
Some sort of airborne detection system like a Ka-31 or rigid airship with radar and IIR sensors and Lidar along with passive sensors that detect signals from drone controllers and from video streams from cameras on drones to locate the drones and the operators.
The blimp might operate at 5km altitude so above small arms fire and MANPADS range.
You would also expand IADS to include anti drone vehicles and units and systems that operate with pretty much everything else.
A Tigr with a gun and jammer turret with perhaps a 23mm cannon from the Shilka with air burst shells and maybe a belt fed shotgun round for close range engagement... perhaps using the 23mm calibre 8 gauge shotgun round used in the KS-23 riot shotgun used by Russian police... being turret mounted the extra recoil and extra weight is not a problem, but the extra reach and extra projectiles in the buckshot rounds would be useful to extend effective range.
Maybe a laser dazzler in the turret too to blind drones over rather long distances too.
Such a platform would benefit from LIDAR too.
Having light wheeled mobile vehicles would make them affordable, but of course the terminator is also supposed to be used against drones too so add a LIDAR... the LIDAR could incorporate a laser dazzler and a more powerful laser option for actually bringing down some more fragile drones like the Aussie ones made of cardboard.
I mean there is footage of them using lasers to cut down a stand of trees... so taking out drones should not be impossible.
By incorporating multiuse equipment you make things better... for instance with T-14... a LIDAR and laser dazzler... the latter can be used against IIR guided weapons like Spike and Javelin as well as drones, and it could also be used against semi active laser homing weapons like copperhead and its more modern replacements.
Modifiying the APS system to also engage drones just makes the APS system more useful and munitions to intercept drones might also be suitable to "intercept" enemy troops approaching the vehicle too.
