Turbinator

I am at the mission near the very beginning where you command a tank and 3 APC's and near the end of the mission a C130 gets shot down, and once you find the wreckage, the voice-over tells you that you need to us a UAV, to check out 3 possible locations as to where the survivors are. This is where I encounter the problem. There is text telling you that you can control the UAV from one of the APCs. After some wreseling with the AI to make the APCs stop moving. I went in to all 3 of the APCs in my convoy, and -none- of them have anything to do with any UAV, or any UAV options, just the standard gunner, commander, driver seats. Now what? :confused:
