MBT/KPz-70 accuracy discussion

The MBT/KPz-70 is armed with a 152mm gun and was designed to fire multiple types of ammunition.
in game it cant only fire HEAT, ATGM and APFSDS.
IRL it had HE as well as flechette (anti personell) (which can be ignored in game).
While the post linked above states the ammo, here is the proof for the tank using the ammo

@David_Bowie may i also ask if you know anything about the internal space of the turret armour of the MBT/KPz-70 being used to store fuel (as an NBC protection measure for the crew)?
I read that since fuel helps absorb nuclear radiation it was utilised as protection which would give the tank in game some form of spalling mitigation
