Okay. I'll use a specific example to answer that.
If by chance you are working with allies in a place like Afghanistan and you happen to be out in a forward position being attacked, and the only air assets you have happen to be American air assets equipped with cluster munitions, your knowledge is not of what is going to be dropped on you at that point. But certainly you're going to call on the assets that are in the air and are specifically there to assist you.
If they're coming in and they drop a load of ordnance to provide some defence for you, it may well be cluster munitions or it might be high explosives. You're not in a position where you will provide direction at that time on the load of munitions, but you will have a call upon it.
