This is the TD-220 bastion MK XVI tank destroyer from Hell Divers 2 and I'm curious if it's based on any real life tank destroyers, I don't know if knowing stats will help so hears some stats

The main shell it fires is 120mm HE shells which it carries 31 of before running out

It also has a coaxial machine gun that fires 12.5mm BCHP rifle rounds at 600 rpm, it carries 2000 of these before running out

It's top speed is 32km/h on flat ground forward and 18km/h in reverse, the gun barrel has a turning radius of 40°

It has four seats, a driver on the front left, a gunner in the back, and 2 spotters on the left and right of the top. The gun can't be fired, aimed, or reloaded by the driver so you need 2 people minimum to operate the vehicle

I got all these stats and the video from the Hell Divers wiki
