Seeing this upgrade of an older t72 raises the very interesting possibility that there is not just one tank program,the karrar,which many of us,myself included,thought was going to be a mixture of brand new tanks built to this standard as well as the older t72s being rebuilt to the same karrar standard.It now seems possible that there are in fact 2 tank programs,one dedicated to building a brand new tank,the karrar,and another program which is an upgrade for the older t72 that no doubt uses some karrar technology but is not a total rebuild into a karrar.
Theres a hell of a lot of surprises coming out of iran right at the moment.
