The goal in this mission is to escort a high-value target, but you will only have access to drones in this mission. For a good part of the mission, it's best to control one of the Dragonfires, as this gives you a good vantage point against enemies on the cliffs. The only real problems will be the tanks, but ASDs will like give you some power to use against them.
One of the first things you should always keep an eye out for are infantry with RPGs. They can cause a lot of damage to the convoy, making this mission a lot worse in a matter of seconds. Actually, it is best to just keep control of a Dragonfire and designate the other two units to attack the tanks when you happen upon them.
As you're going along, the convoy will sometimes stop and this will be because of IEDs planted on the ground. It can be a little difficult to see them, but they can halt progress. There will be a few helicopters later on in the mission, so make those a priority whenever they come. As long as one piece of the convoy makes it to the end, the mission will be complete.
