I may have a different version than you, but here's what I have for some units:
Ghazni Spears
Code:
and hidden_resource khorasan or hidden_resource e_iran or hidden_resource afghan or hidden_resource punjab or hidden_resource sindh
Daylami Infantry
Code:
and hidden_resource khwarezm or hidden_resource w_iran or hidden_resource e_iran or hidden_resource khorasan
Ghulam heavy Foot archers
Code:
hidden_resource khorasan or hidden_resource e_iran or hidden_resource afghan or hidden_resource punjab
This being the old map of AOR: http://img525.imageshack.us/my.php?i...regionsik5.jpg
For now, you'll need to refer to the EDU and check. I think for 1.1 we'll release documentation of unit's regions they can be recruited in. Not sure.
