In this mission you will find yourself on AC-130 plane, which shot at hostile forces in previous mission. It's equipped with 3 different guns (25, 40 and 105 mm), that can really make some mess.
Wait until you are instructed and then destroy a vehicle (#89), that will park next to a church (#90). When attacking the enemy, remember not to damage this building or else you'll fail. However you shouldn't hesitate when it comes to the infantry - it's really dangerous for Price and his team. Remember not to shoot at British soldiers. To make it easier use the IR. It will help you in distinguishing friends from foes.
Attack enemies coming out of the building (#91) and listen to your crew's helpful clues. During the attack, Price's team will be heading towards the main road and will finally reach it.
Two vehicles will show up on the road (#92). They'll be taken over by the British soldiers. Then there'll be another village with enemy's ambush. As soon as the buildings are in your range, attack (#93). Destroy all the vehicles (including a tank), and kill the infantry. Then destroy U-shape building to eliminate soldiers with RPGs. If you're quick and accurate enough, ally vehicles will get through this part.
The last point of this great escape is a scrap yard (#94). Soldiers will get out of the vehicles to wait for an air transport - and you'll have to protect them. Focus on the 2 biggest buildings (#95) as enemy soldiers will be coming out of them. Eliminate any reinforcements that will come and watch out for your allies. After a while helicopters will come (#96). Kill the rest of hostile soldiers and wait until Price and his team flies away.
