Everyone,
I am replaying sandstorm and in the first mission you are given the task of capturing the cargo trucks. I've not figured out how to do it!! I've captured the town I've blown the trucks up I've cut them off, each time it says the British destroyed them. Any thoughts?

I was never able to "capture" any of the trucks even when we were beta testing this DLC. British usually blow them up as soon as I get close. Think it's just worded wrong is all.

I could never do it either in the beta!! Thought I was doing something wrong!
