Would love to see T-72, but knowing WG... they would call it the "Object 172M"
Its the same reason they didnt add the t-64a, but added the "Object 432U" (A t64 prototype with a 90s modernisation package, really?)
Well some info about the Object 172M while we're at it, while its hull was made from composite armour with extra 20mm of RHA armour slapped on it, its turret was completely made out of cast steel. Suprisingly, while the armour was modest at its time (1970s), the cast steel itself could reach up to 410mm of effective armour, which was insane considering there was nothing but steel in that turret.
Also a quick rant, Im suprised WG has not tried to implement a t-72 or t-64 into the game yet, honestly it feels like if you didnt add an AK into a fps gun... Its such an iconic tank. They say that they dont want to deal with people ranting about how unrealistic the stats are so thats why they dont add tanks that really existed, but is that truly the reason? Or are they just lazy?
