AK has evolved into AK-I....And i think would be around 5 million per unit... considering the fact tht mbt-2000 was sold at around 4 million us$... and uses chinese sub systems,smoothbore etc... while AK uses HIT built gun,lecrecs transmission(SESM ESM500 5-speed automatic)... 1200hp engine.. catherine,thales and sagem(ToT TO Pakistan) built FCS and imaging systems,GIDs built IBMS,GIDs ATCOP LTS786P laser warning sensors,hunter killer ability and GIDs upgraded VARTA-1 system...fires upto 9 rounds per minute...with a capacity of 39 rounds...uses same composite armour as ALTAY (GIDs shared armour tech with turkey under a ToT agreement)...etc etc... its a medium wieght mbt and on specs is superior than T-90M...Plus AK-II would be a heavy tank..
Morocco and Peru also use a scaled down version... little brother of mbt-2000 VT-1A....Also its said to be in service with myanmar army.
