VT4 MBT with drone jammers (vertical rods) mounted on top of its turret, which has a jamming range of 1km. This has been the theme this year. Many of the vehicles on exhibit now feature some kind of drone countermeasure devices. Moreover, VT4 now carries two UAVs on the back of the turret that can provide up to 10km of reconnaissance range.
But its clearly has a barrel from 2A46 though.More likely a 105mm gun,a recoil force from 125mm gun fire will to be much for a light chassic.
