8 axles is probably too long for a tank.This almost certainly is not Chonma-2 and instead is likely heavy tank Songun-2.
North Korea has both main battle tank and heavy tank categories in military.
Baseline Cheonma-ho including heavily improved such as "216" is former.
Compared to much larger and heavier Seon'gun-915 being of latter.
Raised engine deck is different and probably house MTU-883 clone.
Overall tank is larger by every measure, probably 8 axles not 7.
