This post contains minor spoilers so everyone that haven't finished this compaign, ignore it.
After finishing the compaign these are all the problems I found with it on v1.08:
1. At mission 2 sometimes the choppers lift off immediately after landing killing half the squad as they eject 50m in the air.
2. At mission 6 (i think, the ambush one), the chopper at the end did not land and I had to replay the mission to make it work (maybe one time problem). Another problem was that from the convoy only the UAZ showed up, then the large force came, and after dealing with that i went looking for the rest of the convoy myself. It was taking a break somewhere half between the base and the ambush position with everyone outside vehicles, again one time problem but it happened the only time I did not take the first base fast enough and had to kill off those mechanized infantry reinforcements.
3. Mission rating is always +1, no matter the score.
One possible improvement could be more variation in squad size and starting gear, which were almost identical all the time. Only minor changes. As missions progress more weapon types and gear should become available.
Compaign could have been longer too But of course this is because it was a great compaign. More stealth missions, too much artilery support.
The end was dissapointing too, it was realistic (how could a small island declare war on the US) but it gave me the same impression like the Armed Assault compaign where the RACs were murdering civilians and they got away without punishment.
