scenario bug?
 

Hello i'mplayng Assall Uttar scenario from PAK side VS AI. and i have found my m47 and m48 useless tank.
Is possibile that centurions after 6-7 hits scored are still operational? my 90 mm are useless against sherman and amx 13. but the centurion are invulerable. Indian infantry are alweys in line and after a hail of fire from my tanks they reply with 2,36 bazzika and voila a m47 after another KO.
What a i can do?
are there same trick to study or i must play vs ai in this manner? Help!
