To be honest, I have serious doubts about the practicality of the Terminator. Compared with infantry fighting vehicles, the Terminator’s main advantage lies in its ability to continuously suppress enemy soft targets and lightly armored vehicles, but this advantage does not seem particularly important. What matters more are better sensors and a higher level of information integration.
Then I thought again: perhaps the Terminator’s real advantage is its ability to better protect other members of the Type 100 armored vehicle family that are equipped with vulnerable sensors. Enemy soft targets and lightly armored vehicles may be able to easily damage exposed sensors, so suppressing these targets could indirectly enhance the system’s situational awareness.
Terminator mostly is a special case vehicle that Russians needed in Chechnya, they wanted a tank level armored vehicle that had a high angle of fire meaning 45 degree elevation to hit enemy fire positions, especially AT teams while in a urban setting.
Cause BMP-2 couldn't do the job.
So they wanted a tank with an AA gun on top of it , so when the convoy drives though a main road in a city , they have a quick respones option suppres infantry in elevated positions.
But that job now days is given to drones , also it can be solved by better combat info sharing though other assets, so I doubt is is for ground support role.
My guess is that the twin 30mm is for anti-air and anti muniation role that a tank compaion need now, they are just too much guided munation equivlents that you might run into, and sensor platforms with thermal sight that can see your ass glowing in from a KM away that evey platton need an air cover bubble of at least 2KM .
