Sangin i have found is practicality useless if using AI, they just get stuck everywhere. There seems to be invisible objects the AI cant path through and even the low stone walls give them major pathing problems. Lots of the building will allow the AI to enter but never leave, I have spent hours backing vehicles up to doors trying to get the AI to enter the vehicle and rescue them from buildings. All very unfortunate as it's a gorgeous looking map with some interesting tactical situations available.
