 We're going to go into a field-based demonstration where we're going to take the capabilities out to the field and we're going to get it in the hands of soldiers. And the soldiers are going to take it and tell us what they think of it. They're going to use it. So usability and simplicity and similar looking fields are really important concepts here because soldiers need to be able to learn the system quickly. It needs to be somewhat intuitive to use. And so a lot like the iPhone. The iPhone is very intuitive capability.
