A main battle tank, made to be big, heavy and expensive by real world standards. There's a whole technical write-up for this thing, but that's too much - it has a 128mm solid propellant gun, a nice, thick layout of composite armour, an up to date fire control system, hyperbar engine with hydractive suspension and a solid APS. It *does* have a conventional transmission, and there're a host of other things I can improve - but that's what it's all about, I guess.

Maybe a 125 mm gun is better due to the ammo being more common than a 128 mm ammo... [not that an adapter is hard to make...]
if it only was an actual tank used by an army

Here, have a three point response!
- Alas, tank guns and the ammunition they fire are a bit more complex than making 'adaptors' - I can think of rather a lot of armies around the world who'd thank their lucky stars if it were that easy! Two illustrative examples make this clear. The first: the Japanese Type 90 tank has a 120mm gun just like its successor, the Type 10, but it's actually incapable of firing the ammunition developed for the Type 10 because its 120mm gun is incapable of handling the pressures of the new ammunition. The second: in trying to replace the rifled 120mm of the Challenger 2 with a smoothbore Rheinmetall 120m, the British found that there wasn't enough space in the Challenger turret as designed to store the one-piece ammunition of the new weapon (because the old weapon used two-piece ammunition).
- 125mm ammunition isn't actually that 'common'! Because of the limitations of various T-series autoloaders and the different ammunition that had to be designed for different tanks, there're a huge amount of different types of 125mm ammunition that isn't quite interchangeable between tanks. Legacy T-72s have incredibly cramped autoloaders, which means that they have to use shorter ammunition than that used on the T-80 series. Early T-90s use the same autoloader as the T-72 (being T-72s themselves), but later T-90s are rebuilt so that their autoloaders can handle T-80 length ammunition. Finally, the T-14, which stores its ammunition in a vertical turret autoloader and can handle longer ammunition than previous T-series iterations, is probably going to end up having its own new and incompatible series of ammunition, making the whole damn thing even more complex.
- Thankfully I designed the HT9A7 for a fictional world in which real world ammunition concerns aren't as valid!

I understand, but still... 125mm is more common that 128 mm
Besides, Yugoslavia's M-90 Vihor had an autoloader base on the Soviet one from the T-72, but completery redesigned and it's complexity reduced by 80% while the rate of fire has been increased by more than 30%

It's a demining roller - puts pressure on stuff under it, and pressure on mines with the right fuzes makes them go 'boom'.
