1-In mission "moral fiber" after seizing first objective, two friendly helicopters land and unload some units, one of them land inside complex too near to a tower and after taking off hit it and take damage so fall down at same landing place.
also because of bad AI driving behavior sometimes leader squad's hunter stuck in some obstacles like trees so he left behind convoy and when player disembark near pyrgos, because of his distance to squad leader, where he's still stuck, mission fails.
2-In mission "preventive diplomacy" there are several issues too:
kerry squad members have different weapon of their rules, such autorifleman has AT and ATsoldier has autorifle.
sometimes artillery support disappears, specially when you are using that trough UAV camera.
the blackfoot from CAS mission never fire on anything include enemy armors and infantries.
mission completes although there are plenty of enemy infantry units in city and player is still fighting against them.
3-In mission "status quo" voice of journalist and niko can't be heard, only kerry has voice.
