OK, here are some discussion about this MBT-72 on StrategyPage.com:
"The Russian is also working on a BMT-72 HIFV which looks like a MBT but in fact a Heavy Infantry Fighting Vehicle(HIFV). May be in future ,this will be the standard armour arsenal in most army and MBT will continue to play a part in the 21th century armour warfare in other form."
