Main mission objectives:
1) Destroy Blackhawk remains
2) Evacuate Lt Rosen
Possible drop zones:
A) The southern road
B) Near the hacienda
This is going to be an exceptional choice, because I will recommend that you choose a second drop zone. It's located near the hacienda, to the east of the main building complex. This is going to be a much better choice if you plan on acting quietly. You will be able to complete this mission without raising any alarms. I wouldn't recommend continuing to play if this happens, because the alarm would be equal to additional reinforcements and you would have to kill all of those soldiers in order to succeed. If you plan a stealthy approach, you will only have to take care of about 15-20 rebel units.
Just as before, you won't be playing with your entire Ghost squad. Instead, you will only have one teammate at your disposal. I wouldn't recommend choosing soldiers from other professions, because it won't be necessary. Rifleman unit seems like a best choice here. As for the weapons, if you plan on taking out enemy units one by one, you could consider choosing a sniper rifle, however it must have a suppressor attached. Otherwise you should stick with your default gun, especially since it should already be properly silenced.
