"This information can be acted on by commanders at higher HQ, and conveyed to others on the ground or in the air, so they know what they face and can do something about it."
Scott Harris, president of Lockheed Martin, says one benefit of UAVs is that the information they glean can be fully integrated with everything from data from space to what is happening in the field, to form a complete picture.
"UAVs are very interesting and complex," he says.
"Everybody is working on them and deploying them. Militarians can't get enough of them. We have a broad range of programmes, most of which I can't talk about."
One reason he is not talking about it is that UAVs are increasingly carrying weapons, so developments have to remain secret.
Yet it seems their increasing use on the battlefield - and in peacetime for mundane tasks such as traffic patrols - is now fully assured.
